Mark1971
I have read on many forums about the fault which I was experiencing with my 2004 1.6L TDCi CVT C-Max. On pulling out of junctions and roundabouts and recently when the Ford Engineer went to overtake, the engine would lose power for a couple of seconds. I don't need to explain just how dangerous this is, especially when trying to cross the A1!

Anyway, touch wood, my local Ford garage has resolved this so I am posting this hoping that this will help some of those also affected by this.

I gave my Local Ford Garage my car with instruction that I did not require the car for a week so they had that time to look into it. After several drives with the scanner attached, witnessing random fault codes flash up then disappear (no fault codes are shown while the car is idle) the car fails to accelerate when the engineer went to overtake. Thank God, they now believe me!! Well, several engineers have put their heads together on this one and this is what they have come up with:

1. Cleaned oil contamination from the Air Mass Mater
2. Inspected and cleaned several sensors and wiring connections
3. Re-Routed the wiring loom in several places (I take it for interference reasons)

On taking the car out afterwards, no fault codes were displayed at all! :D

I have taken the car back and I must admit, it runs so much smoother, quieter and as yet it has not missed a beat. I have read on several forums that people have had their car in several times and are well out of pocket so hopefully this may be of use.

I did happen to have the intermittent low fuel warning warning appear despite the actual fuel level but this is known fault and is rectified by a module software update.

Thats a good result and thankfully it was resolved before you had any accidents due to the power loss.

Hopefully this bit of info will come in handy to anyone else who may have this problem.

Sorry to hear about your c max mate.I had the same prob mate and im sorry to say they could not find the problem with mine.It used to hesitate at around 1700 to 2000 rpm.It nearly cased a bad accident on the motorway as it hesitated so bad on the outside lane doing 70mph the car behind skidded and almost hit me as the brake lights where not on to warm him behind that i was slowing down rapidly.I took it back to fords many times over the year and a half i had it and changed the egr valve three times and updating the firmware countless times .It seemed lovely when i got it back each time but months down the line it would happen again.In the end i traded it in for a focus ,i just about had enough of it.Mine was a 54 plate 1.6tdci ghia.

Mark,

I have experienced the same problems as you with my CVT auto. I am keen to know whether the work done to your car has provided a permanent fix.

I've had very similar work done to you at several attempts over the 14 months I've owned my C-Max (July '04 Reg):

Engine Management Software updated - problem came back within a day or two
EGR changed - problem came back after a week
PCM software version changed, wiring changed - and I suspect sensors cleaned and checked - problem came back within a couple of weeks

The problem seems to get gradually worse over time. So far it's lasted about 3 months each time before it's so bad I can't stand it any more.

My car is in the main dealers today to look at the same hesitation problem, plus a problem that happened the other day. I was doing 80 on a dual carriageway and lost power, the car slowing to 50mph. Putting my foot down caused the revs to rise, but no increase in speed. I stopped in a layby, switched off and on restarting the problem wasn't there.

I'm expecting a big bill and no permanent fix - again. Hope I'm wrong.
Mark1971
I don't believe it!! On the way to work today you'll never guess (I'm blaming you by the way c-maxxer) I came off an island, put my foot down and it accelerated about 1MPH faster per second. I floored it, as far as the pedal would go and the gearbox changed down, rev shot up as you would expect but would not accelerate!

JUST HOW F%*&ING DANGEROUS IS THAT!!!!

I need to find the time now to get the car back to the dealers. It's as though the car had gone into a safe mode so I'll have to recheck the manual in a minute. I had about 1/8 tank of fuel at the time and when I mentioned this to my partner, she said that she also had an experience with this amount of fuel in the tank since getting it back from the dealership.

The original fault, the hesitating and short burst of power loss has not reoccurred, but this more than makes up for it! I can't for the life of me think what would cause the car to behave in this manner and not accelerate even though you can be in any gear and engine at any revs!?

I have reported this to watchdog and I hope other C-MAX owners will do the same as this is so dangerous and obviously not an isolated problem! I do not see why we should charged for what is clearly a design fault.
Mark1971
C-MAXXER,

I've been looking through the manual - see atached.

Page 33 explains about that acceleration will be noticeably reduced if the Electronic Accelerator Control (EAC) detects a malfunction. Sounds like just the fault that we are all experiencing!

Maybe the 1/8th of a tank is a red herring, I'll have to wait and see again and run it to that level (oh god!) or maybe the whole ECU is screwed up!
c-maxxer
Mark,

Thanks for posting the extract from the manual.

I've had more fun and games since my last post - the garage charged me £200 for replacing the crankcase breather hose plus cleaning the MAF sensor. This improved the problem for one journey of a mile, after which it seemed worse than ever.

I then got a total loss of power on the motorway - co-incidentally just as I was near the dealer. I crawled into the garage and left the engine running whilst getting a tachnician to confirm there was a problem. He did - but of course they couldn't see the car then - it had to be booked in.

I was fed up and got Ford Customer Relations involved in advance of taking it back to the dealers. The dealer has now changed his attitude completely - claiming there are no fault codes, that Ford Technical say these problems are "a characteristic of the car" and they can't do anything.

The car has since been back to the dealer again for them to drive around for four days "no fault codes, no action possible" and is booked in again for early January, when they're going to offer me a courtesy car for the first time.

The garage is going through the motions - very slowly, but I'm not hopeful of a proper fix. I just hope the car doesn't pack up in a critical place. I'm very close to saying "f*@k it, get rid", losing 5 grand to replace it and never buying a Ford again. :angry:
Mark1971
How very bizarre! My C-Max went into the garage yesterday (Monday 1st December) following a phonecall to them on Saturday after I had received a receipt for £177 for not being able to diagnose the fault yet again and for taking the fuel tank off! During my very angry phonecall, I was told that this was to check the fuel tank and make sure that there was nothing like a...... wait for it........... a carrier bag in the tank!!!!! Wot the F*#k!!!

Well I dropped the car off last night, picked up my 'courtesy car', a 2001 Ford Fiesta with broken headlamps, no washer fluid and vapours for fuel. I called them this afternoon and yet again they explained that there were no fault code apart from one which, related to the traction control, although they could not be sure. They need more tests and have been in touch with 'Ford' who could not really help other than advise to check all connectors and sensors once again.

I'm sorry but as an IT Professional, I need to be able to fix faults without a piece of software telling me what is wrong. Do all Ford engineers know what they are doing or have Ford made a huge FUBAR in releasing a faulty car not fit for purpose?

Well so far, between us, we can say that it is not the MAF sensor, not the crankcase breather hose, not due to interference and so no need to re-route cables, not due to oil contamination in the Air Mass Meter and definately not due to carrier bags in the fuel tank (twats).

Like you c-maxxer, I'm regretting ever coming back to Ford!
Mark1971
c-maxxer,

I have just watched your video - this is [u]exactly the same [/u]as mine!

When it hesitates, if you look in your rear mirror, all you can see in the following cars headlights is a plume of smoke. This is so annoying that this has to be down to faulty or badly designed sensors and Ford are just interested in charging for parts and time taken in incorrectly diagnosing the fault.

AAhhhhhh!!!!!!!!!!

I hope you have contacted Watchdog. I want everyone reading this who has a similar fault to do so as this seems the only way this will ever get resolved
Robcmax
Hi 'Mark1971' & 'c-maxxer'

I' ve just read your posts with interest (& some dismay!) as the problems you describe are exactly the same as mine. At first I put the slight hesitation down to being a quirk of the turbo diesel, but after the engine warning lamp came on I booked it into the garage to be checked - I was told that the ECU software needed to be updated and that this had ([i]probably[/i]) cured the problem. I've continued to put up with the occasional hesitations and puffs of soot until today when I suffered a complete reduction in power, the same as commented in a previous post. I'm not a car mechanic but I am an engineer, and I'm convinced it's an EAC related problem - anyway, I'll be taking all the useful info you have provided to the garage again to put their customer sevice (and warranty) to the test.

I'll let you know how I get on.

Thanks

Well, I have the car back. Mechanics have looked at the car again and after 2 days, 1/4 of a tank of fuel, they still cannot find anything wrong! I have been told that there is nothing wrong with the engine, wiring and sensors and that it can only be the 'Speed Sensor' in the Auto gearbox which, just so happens to be a sealed box and costs £4k.

I think it is time to get rid of this damn car and this whole experience of build quality, customer service and lack of assistance by a dealership has made up my mind never to buy Ford again! I always did fancy one of those Chrysler PT Cruisers anyway.... B)
mickeej
Hi mark think I have bad news about your C-Max. have the same problem with mine, and have been trying to sort it for 3 months. My brother in law is chief tech for merc and has helped me track down the problem. the engine is hesitating at about the 1800 rev mark on a part throttle, feels like its braking , this is due to a fueling problem. if you remove the wiring loom from the air mass sensor the problem will stop and this proves a calibration error in the ecu. the firmware upgrade you got will only last about 3 months as the ecu will re learn this mistake. Citreon who make the mechanical parts for this engine had the same problems and they will tell you they changed the ecu and fixed it.
today I found out that ford also changed the ecu from 2006 on. and the new cars do not display this problem. the problem is the chip and not the software and this is why the problem comes back.I intend to replace the ecu with the newer model and this should sort the problem but the cost will be near £700, but I think that is a bargin compared to 3 monthly updates at £103 each and also the fact that the problem is also blocking the egr valve and will eventually kill your cat
Hope this help all as ford are keeping stum while people are happy to pay for updates :angry:
c-maxxer
Mickeej,

I'm very interested in your post, although I'd like to check a few things.

First, is your car a CVT auto ? The reason I ask id if so, I see yours is a 2005 car, one of the later CVT autos. According to the Honest John website, CVT auto C-Maxes were only made between March 2004 and "late 2005". According to the HJ site the hesitation problem affects "early 2004" CVT's. If this were the case, you shouldn't have a problem to start with!

Isn't the ECU is specific to the engine / gearbox combination rather than just the engine ? Putting an ECU from a 2006 or later manual car could cause some unforeseen compatibility issues ?

Also, wouldn't the engine ancillaries (turbo/EGR etc) be updated over time as well, so putting a new ECU on an old engine could create other unforeseen issues ?

Don't want to put a downer on a potential solution though - I'm keen to see how you get on going down this line. Please keep posting !

C-Maxxer
Mark1971
Mickeej,

That's very interesting.... plus, I hadn't read the HJ website. I'm due to see the garage shortly to pay for the time spent miss diagnosing the fault so far, I'll be taking a copy of this with me and going to get them to check.

I can't even get mad now, I'm just sat in disbelief as HJ's report was written in April and still deny there being a problem. I know times are hard but trying to convince me that i need a new gearbox at £4k?!

If you do go ahead with this Mickeej, please let others know how you get on here but do bare in mind what c-maxxer is saying, we wouldn't want you unecessarily lining the pockets of Ford anymore than you already have, unless of course you can get your hands on one out of a scrappy.
Mark1971
What can I say....... I took the Honest Johns printout to the garage this evening and asked if they would check the items mentioned. I had a very rude and irrate mechanic instantly dismissing all the points listed and basically made out that I did not know what I was talking about and that noone at the garage had experienced the issues that I had been complaining about.

WELL, SLEAFORD FORD, CHECK THE FIRST JOB CARD (ATTACHED TO SAVE YOU LOOKING) AND READ WHAT THE FIRST ENGINEER WROTE ON EXPERIENCING THE FAULT FOR HIMSELF!!!!

I weren't going to mention the garage, but my partner no longer wishes to buy her new Focus due to their arrogance and lack of customer service skills, but instead is looking at her second choice which is a Honda Civic. I will never buy a Ford again and I am currently looking for a garage to accept my car as part-ex. These bills have also gone as a complaint to Ford Head Office and I will be contacting the Citizens Advice Burea in the morning.
You would have thought that in the current financial climate, They would be making every opportunity to raise business rather than turn them away.
c-maxxer
Mark,

Sorry to hear that your Ford dealer aren't taking you seriously. I've been at the end of my tether more than once with mine.

I'm going to persevere until they've had the car with them again for another week. I'm expecting them to say "no fault detected" again - after which I'll have gone as far with them as I can - other than complaining to someone else. I am making a collection of web posts with people with the same problem - may be worth a punt to What Car or Watchdog if there's evidence of lots of people with the same issue.

Trading the car in is a drastic step - I don't know how much you paid for yours but I paid £8.5k just over a year ago. Parkers says about £4.5k trade-in value now. Ouch.

I think I might try an independent ford garage to try and come up with a fix before going that far. Perhaps "chipping" the ECU might get round the problem ?
Mark1971
C-Maxxer,

I have thought about 'chipping' it too although I was hoping that Mickeej would hurry up and prove it with his replacement ECU from a 2006 model! LOL

If it does prove to be the answer, I may just try this method before I part-ex it in as I have already spent £600 for nothing as you know. I'll have more time this weekend to trawl through the internet and look at the feasibility of it, and prices, although it has to worth a shot. I also received a reply email from Ford HQ today wanted me to speak to their customer relations team. They can ring me as far as I am concerned, I have wasted far too much money and time speaking to idiots and I will not go back to Sleaford Ford until I receive an apology for their rude and arrogant bahaviour and we both know that will never happen!!

I just thought, there may be a business oppportunity here C-Maxxer - given the amount of faulty C-Max's out there, I'd better dig out my old chip programmer? ;)

*******************

I could have purchased a complete 2006 TDCi engine on ebay (Item number 320321750494) for the same money I've just given to Ford, for doing nothing!!
c-maxxer
Mark,

That engine looks like a 1.8 !

Chippping may be the answer, but doing it properly wouldn't be simple. Certainly the early chipmods were crude things that did nasty stuff like allowing higher turbo boost that could wreck the engine.

The problem we're dealing with is potentially a bloomin' nightmare of complexity to sort properly - effectively doing the development work that Ford haven't done thoroughly.

The issue involves could easily involve the alteration and co-ordination of :

turbo boost
turbo geometry
fueling at different throttle settings
egr position
gearbox sensor inputs to the pcm
engine sensor inputs to the pcm
pcm outputs to the gearbox and engine
etc. etc.

Since these cars are rare, no-one will have done any mods like this before. Hooking the car up on a rolling road is probably essential - so would be expensive with no guarantee of success - and would need technical experts that are up for the challenge. Still, it may still be worth investing a grand or more if the alternative is losing 4 grand or more on trading in.

I'm going to take my car to an independent garage who specialises in performance Ford upgrades in January and will at least discuss this idea to see if it has any chance.

Guys,

I can no longer play Russian Roulette with the lives of my family and after breaking down 4 times during a trip to Essex on Boxing day, I have made up my mind.

I pick up a Vauxhall Vectra in the next few days and am turning my back on the cowboys at Ford for good.

I hope you have more luck than I but losing the 2.5K in 8 months while owning the car does not even register after having to cross busy motorways and A roads while randomly losing power.

I have registered my complaint with Ford HQ who were not really interested, Citizens Advice and Watchdog in the hope that Ford will come up with some sort of resolution. Although, I would suggest that you do the same as I and get rid if your car is doing the same as mine before someone has a fatality and not keep throwing money away by visiting dealerships and paying for them to just run diagnostics who do not care!

I am going to do everything in my power to make sure that as many people as possible hear of this as this is not an isolated case, but one which Ford know about, so far have been unwilling to rectify and have put the lives of my family, my own and others at risk.
c-maxxer
Mark,

Sorry that you've decided to cut your losses.

I took my car to an independent Ford tuner before Christmas, who showed me the diagnostic output. When he hooked it up it came up with a forest of error codes - data loss errors, throttle position sensor errors, turbo boost errors and so on. He wasn't convinced these were all genuine errors, but could have been caused by the main dealer disconnecting components. He cleared the codes and we went for a short test drive. Although the car hesitated, no fault codes were recorded. So the Ford dealer may have been telling me the truth when he said that he couldn't get it to fault when he had it.

My car lost power at speed three times in four long trips over Christmas and hesitates badly at every pullaway from standstill. It was already booked into the main dealer today and they've given me a courtesy car for the week. I'm not prepared to drive my car again unless they do something. I too am at the point of despair with all the hassle and at the point of trading it in - if I can.

Did you get a resonable trade-in for your C-Max ?
jam-cmax
hi i know this may sound daft but i have read on another forum about people having this problem and by using millers diesel sport 4 this hesitation problem got better :wacko: i know it sounds daft but thought id let you know ;)
Mark1971
c-maxxer,

Didn't get a good price for it really, paid £6.7k for it in June last year, got £4k for it part-ex. However, the things that I took into consideration are the fact that this required yet another visit to the garage, in my opinion, which would encounter cost, the fact that I have no faith that a Ford garage will be able to fix it and also the fact that due to the financial climate we are in, you can get a much better built car with a higher specification for very little money.

I would advise you to seriously consider other alternatives to handing over money to Ford to diagnose an unfixable fault and also realise that you life is worth more than a couple £k should your current visit to Ford turn out the same way as all the previous visits. I do hope your garage finds the fault together with whoever ends up with my car, I do feel guilty part-ex'in the car unlike the dealer who sold me the car, I had just had enough of not only the fault we are all talking about here but also the creaks from the door seals and the push fit plastic panels.

I just didn't know where to take it other than my local Ford dealership who, as you already know, I will never visit again, ever!
clair
I am having the same problem as you guys but with a '57 2.0 TDCi, just had a call to say they have reset the EGR (I think). But now I am worried that this will re-occur given all of the comments you have made. I will quiz them when I go to pick it up, I did note that when I dropped it off they did not need much explanation of the fault so assumed they already knew about it.
Fingers crossed it is going to be OK as have some motorway driving over next couple of days.
c-maxxer
Claire,

There was a known problem with early 2.0TDCi's of EGR valves sticking that resulted in virtually no power. The EGR valve was redesigned and the engine management software modified to "cycle" the EGR to stop it sticking. Your car has these modifications as standard though, so it's surprising you've got an issue.

The CVT hesitation problem that occurs is different and hasn't a known cure that I'm aware of.

The Ford technicians I have spoken to in my many trips to the garage say that EGR faults on diesels are the bulk of the problems they deal with - and it's due to the tougher pollution control measures on modern cars. Still, you'd think that the manufacturers could do better in coming up with reliable solutions.

I have a theory that lots of short trips are bad for modern diesels and that's one reason why they clog up and suffer these problems. Is yours one of these ?

Fella, dunno if you are aware of this, possibly so. Just because Mickeej's vehicle is registered in 2005 it could easily have been built in early 2004 and stood in a stock yard somewhere for a year before it was sold and registered. I dont know C-max other than they are probably the most problematic model Ford have EVER produced. But you keep your eyes peeled for this anomoly to prove my point. Ford changed the focus from the Mk1 (indicators in bumper) to Mk1.5 (indicators in headlight unit) mid 51 plate. Personally locally to me I have seen a good half dozen 02 reg motors with indicators in the bumper (ie Mk1) and even 1 52 plate with the indicators in the bumper. These can only have been built before the factories changed to the Mk1.5 design late 2001 then registered with DVLA and given their 02/52 registration marks.

Ref my post of 5th January saying my car was in the dealership - for the FIFTEENTH time looking at the hesitation and going into limp mode problem.

Dealer finally said it was ready yesterday. Was charged £46.00 parts only for a new MAP sensor (manifold absolute pressure). Dealer said Ford Technical had been consulted, fault found and rectified. I drove 10 yards in the car and could tell there was "absoulutely" no difference.

Dealer then says - after me making a scene in service reception - they would refit the old parts and give me a refund for what they've done. No mention of a fix. This is on a car that broke down on three out of four long trips over Christmas.

Spoke to Ford Customer service who've promised to get Ford Technical involved again.

I'm out of patience. Car is going to be traded in, which is going to cost me £thousands, but I'm now resigned to it.

In my view this hesitation problem with the early CVT auto's is an issue that Ford are knowingly doing nothing to resolve - because there are too few owners affected. They don't give a stuff for those affected.
Mark1971
c-maxxer,

I hope you have emailed Watchdog reference this as this week they reported similar faults with 2.2 Vauxhall Vectra's, (fortunately I've just purchased a 3.0), so they need to be made aware by as many C-Max owners as possible that this is a problem with these early CVT's also.

I think you are doing the right thing. I only took my car to the garage 4 times to realise that they had no idea what the fault was and as Ford HQ were not bothered on the several times when I had contacted them, the C-Max had to go. You will have lost a lot of money part-ex'ing the car in but look at all the benefits you'll have - you will no longer be putting yourself at risk each time you get into the car, you will be able to chill out and enjoy driving again (I certainly have done) and although you may have lost money on your C-Max, you will be able to get yourself a much better built, reliable car and at cost price thanks to the current financial climate.

It is a shame, put aside the creaks from the doors and rattles from the dashboard, the C-Max could have been a good car if only it had not been engineered by muppets on a budget. Have you noticed the vanity lights behind the visors and that they are the same on both sides, just one is flipped over so that it switches in the opposite direction? Cheap, tacky and really sums the car up.

Go now, get looking on Auto Trader and turn your back on Ford for good. You have given them far too much money for nothing and what have you got to show for it? If you're like me, years off your life through stress and more grey hair!

Take care,

Mark

Car has been traded for a Skoda Roomster petrol auto. Runs like a dream. My biggest regret is dumping my problems on whoever buys my old car.

Sorry Ford, but my experience over the last 18 months means I ain't buying your products again for a long time. You've got problems with C-Max CVT autos - why don't you admit it ?
adamnlauren
Hi guys,

Just registered as I was lead to this discussion via a google search. I have owned a 54 reg C-Max 1.6 TDCI CVT for just over a year. I had the hesitation problems (1500 to 200 revs) soon after buying the car from a private dealer and it would register a transmission malfunction and go into limp home mode until I restarted the engine.
The Ford dealer sent it back the first time with no explanation but the second time they changed the EGR valvue which I have since learnt is a common fault. A year down the line and the problem returned with avengence. This time they changed the EGR valvue again as well as the mass air sensor but said they were still getting the transmission malfunction and I needed to take it to an Automatic Gearbox specialist. I did and he said it was an ECU problem. Went to another Ford garage and they had it for over a week. At one point they thought it was the ECU but now they are saying it is a faulty solonoid in the gearbox and they need to replace the whole thing for £5K.
I can probably drive it around for another 10 months but have a feeling this is only going to get worse. Realy interested in how Mickeej gets on as £700 sounds a lot better than £5K. Have lost faith in computer diagnostics and Ford garages and am starting to feel the rage slowly build.

Any links to other useful forums or info would be really appreciated.

Cheers

Spent £2000 looking for the fault on mine.
Replacement parts fitted as they were finding the fault
Full set of injectors.
New Battery
Fuel filter
Emptied tank of contents
Flush out fuel pipes
Re programme ECU
Full set of injectors again as they said the ECU messed up the first set becauseit was not programmed right (no charge )
and a whole lot of labour
Any how they had the car for three months not weeks yeah I mean MONTHS
They gave me the CHOCKS AWAY GINNER ! and off I flew.
ok I did gain three weeks of fabulous trouble free motoring when one dark evening Stop start
So up went the bonnet and out came my torchbut the battery on the torch was low and it did nt last long whoppee gud!
The bestest timing I could have wished for.
In thr darkness around what appears to be a soliednoid were only to be seen in the dark were short circuiting proofs!
Replaced the partand ok to date.
Question is £2000 got spent on on parts and labour that did not fix it Jim!
I t was a flat battery that eventually repaired the fault.
So you gentle folk out there dont go looking for your faults first thing next moring.
Put on your boots and take out your batteries on the torch and happy searching!

So up went the bonnet and out came my torchbut the battery on the torch was low and it did nt last long whoppee gud!
The bestest timing I could have wished for.
In thr darkness around what appears to be a soliednoid were only to be seen in the dark were short circuiting proofs!
Replaced the par tand ok to date.
Question is £2000 got spent on on parts and labour that did not fix it Jim!
I t was a flat battery that eventually repaired the fault.
So you gentle folk out there dont go looking for your faults first thing next moring.
Put on your boots and take out your batteries on the torch and happy searching![/quote]

Was thinking of buying one of these until I discovered this thread. Some idiot wrote off (didnt stop!) my Skoda Fabia last week in the snow so I need another car! . I would like an auto but as I now have no NCB the 2L petrol auto will cost too much to insure.I need something reliable though and this doesn't seem to be it with the CVT box

Ginner, is yours now fixed then? What part did you replace? Was it the solenoid?

Hi all

If only I discovered this thread before buying a C-Max 1.6 CVT Auto almost 4 weeks ago, the car had done just over 15500 miles and is on an 04 plate cost £5999, in the last 3 weeks its spent most of its time at the dealer where I bought it with them trying to discover the loss of power and car going into 'limp mode'

So far they have:

Reset the ECU
Upgraded the firmware/software
Replaced the MAP sensor ('Mr Mort car will be fine now' they said)

Collected the car on saturday and today took it for a lengthy drive to make sure all was ok, like hell it was after 40 miles total loss of power had to pull over turn her off leave for a minute and start her back up to drive home with it working ok.

A friend of mine has suggested a fuel pump problem but after reading this thread im not convinced, so back to Ford's tomorrow to hand them the keys back and get a replacement or give me my money back. Don't get me wrong when this car is working she's a fantastic drive, if only it didn't break down.

If anybody has found a fix please let me know.

Regards

Mort

Mort,

I feel for you. I bought a lovely model, Zetec but with heated leather seats and when it worked, drove lovely. But you can see from this thread, it is a known problem and like the rest of us, only looked into the issue once online once we had experienced the fault.

As it has only been 4 weeks, try and get your money back as you'll be throwing good money after bad as you can see from mine, c-maxxers and other c-max owners reports. Feel free to print off my receipts and use in your defence that this is a fault that Ford do not know how to fix together with this thread. I'd also recommend letting Watchdog as they'll only pursue a story if they receive several complaints. We need to get the message out there to stop others making the same mistake that we have.

It is a shame, we have all said the same 'It would be a gorgeous car - if only it worked!'

If you get your money back, I went for a Vauxhall Vectra, some great bargains to be with those and C-Maxxer bought a Skoda Roomster which I believe he is also pleased with. I personally won't be touching Ford again for some time although I had received crap service and attitudes from Ford staff also.

Good luck
Mark1971
P.S.

If it weren't for the mileage, I'd swear you had my last car!

We had to pull over 4 times (twice each way) on the busy A1M and reset the car - just how dangerous was that!!
Mort
Woohoo!! problem solved :P

Took the car to Ford dealer this morning and she's gone, was told to choose any car we wanted up to the value of what we had paid, so wifey decided she wanted a Citreon Picasso 06 plate just under 10500 miles. :ph34r:

Mark

Thanks for the sympathy and to all the early model CVT owners out there I hope you dont get the same problems as the rest of us here.

Maybe one day I will own a Ford again :blink:

Regards to all

Mort (finally happy)

I too have a 2004 Focus CMax TDCi Auto and have suffered the various power loss scenarios described by other correspondents to this site. The car was hardly away from the garage whilst it was under warranty and suffered the changing EGR valve, draining fuel, replacing fuel filters, cleaning MAF sensors etc etc. The car was towed in about 6 times in all.

I once had a total power loss in the outside lane of the M40 at 70 mph. Fortunately I managed to get safely to the hard shoulder. Waited for 5 mins car restarted ran for a mile then cut out again, restarted after another 5 mins and ran as far as Birmingham when I called RAC. They canme out and could find no fault and it then got me home to Cheshire with no problems.

When it was out of warranty I still had problems and insisted that Ford take some responsibility as I considered the vehicle to have a latent defect in the design which should have been fixed under the warranty. In the end they claimed the power loss was due to a chafed cable which was shorting out and confusing the EMS.

The car has just done 105000miles and I was only thinking it was now running well when the transmission failed completely whilst my wife was driving. I am now told that a replacement gearbox will be £4500!!!!. Despite being a nice car to drive I strongly advise all owners not to hang on to their vehicles too long. I am not spending £4500 to repair a car which is only worth £2500.

Independent transmission repairers cannot get spares and so you have no alternative to go with the main dealer.

Does anyone know where I can get a reconditioned box?

Well Well Well...you never guess what? I am embarrassed to say that i also bought a c-max and THEN found this site....It sounds as if you are all describing my car!!....My symptons are as follows....( by the way its a 2004 tdi automatic zetec)...1. i get to about 1800 revs and the car feels as if its running out of fuel.....2. At 2200 - 2400 revs the "transmission malfunction" message comes up....3. If i switch to driving it in "manual mode", at 2200 - 2400 revs, the engine management light comes on!!.... 4. If i increase speed slowly thus keeping the revs under 2000 the car will drive up to 80 mph with no problem...I took it to the local ford dealer and i quote from the invoice i received, "trace fault to transmission malfunction, spoke to ford engineers..possible fault with turbine shaft speed sensor...unable to locate this part so spoke to an auto gearbox specialist and determined fault is possibly with auto gearbox itself"....The service manager tried to tell me that they had NEVER encounted this problem..which is why they spoke to the ford engineers, who also said they had never come across it!!.... ( I phoned him today and asked him to check out this site! )....the position i am in at this moment in time is a bill for 2hrs labor (£170) although he told me the technician worked on the vehicle for 7 HOURS!!...but he would only charge me for 2hrs...(was this a ply to make me feel better?) Well let me say I DONT...fact is the car is excatly as it was before i took it in, the only difference is i'm £170 out of pocket and none the wiser......PLEASE SOMEBODY HELP !!
rjays
Just as an update....Ive finally discovered when the problems arise...Its when the vehicle needs to change down a gear ( 7th to 6th 6th to 5th 5th to 4th etc) to accelerate whether im in auto or semi auto the problem appears....however to combat this i have now learned to get the revs up.. so in semi mode 1st gear 3000revs then change to 2nd bring the revs back up to 3000 and change to 3rd and so on until i reach 7th..i only change down once the rev counter falls below 2000.... this seems to work fine on mine with no problems at all...what its doing to the gearbox i have no idea but it works..am i just masking the true problem or what?...by the way if the car (in auto mode) changes down a gear to slow down at a junction for example theres no problem.. just when it changes down to accelerate to overtake or going up a steep hill...is this the same as anyone elses?
trignflo
Is this problem only down to Auto's as I have an 04 plate 2.0TDCi manual which has the 1800 -2000 rev hesitation problem, many EGR's in the past...... only done 26K miles since new.... Did any one get anywhere with the tuning / chipping suggestion?

Trignflo
rjays
hi trignflo...not sure if its just auto's...and i personally have not tried chipping

I feel your pain, one and all. Luckily my 1.6 CVT was bought from a family friends garage so all work done has been paid by them. They are letting me use the car until they can find a suitable, manual, replacement. I have had EGR valves changed, Turbo boost pressure sensors replaced, wiring joints cleaned and waterproofed and they paid for a tuning box to be fitted to get rid of the acceleration 'dead zone'.
The tuning box has improved mpg and performance, but not cured the 1600 - 2000 rpm stutter, it just happens at 1800 - 2200 rpm instead now! They have come to the conclusion that it is just an incompatible engine and gearbox combination. I have read about solenoids shorting out, but that was found, by chance at 2am in the morning by the owner. The fault occured while driving home one night down an unlit road, he left the car running and popped the bonnet not expecting to find anything, just out of frustration. Anyway, he reported seeing some sparking (he doesn't pinpoint where though) to the garage breakdown guy and they replace and shield the solenoids. Hey presto, the problem was cured! Could be an old wives tale but sounds plausable to me. You just need to find a garage that is willing to work at 2am with the lights off when your C-Max starts to do it's thing, pfffft.

I have an automatic and once I was at a round about with the heat on max and pulled out to find I didn't have the power I needed, I was also in manual at the time. I have noticed slight power reductions when pulling off but just put it down to my style of driving

Mark,

Thanks for posting the extract from the manual.

I've had more fun and games since my last post - the garage charged me £200 for replacing the crankcase breather hose plus cleaning the MAF sensor. This improved the problem for one journey of a mile, after which it seemed worse than ever.

I then got a total loss of power on the motorway - co-incidentally just as I was near the dealer. I crawled into the garage and left the engine running whilst getting a tachnician to confirm there was a problem. He did - but of course they couldn't see the car then - it had to be booked in.

I was fed up and got Ford Customer Relations involved in advance of taking it back to the dealers. The dealer has now changed his attitude completely - claiming there are no fault codes, that Ford Technical say these problems are "a characteristic of the car" and they can't do anything.

The car has since been back to the dealer again for them to drive around for four days "no fault codes, no action possible" and is booked in again for early January, when they're going to offer me a courtesy car for the first time.

The garage is going through the motions - very slowly, but I'm not hopeful of a proper fix. I just hope the car doesn't pack up in a critical place. I'm very close to saying "f*@k it, get rid", losing 5 grand to replace it and never buying a Ford again. :angry:

The EXACT same thing happens to mine when I take off, just like you I have to give it extra acceleration cause it feels like its dropped.

Hi all am new to forum but boy am glad I've found it
I've owned my c-max just over 3 years and never had so many bills and problems that never seem to be fixed
even our local garage are calling it "the 5 clock Friday car"
I paid 8.5 k now its value seems to be 3k trade in with just 54k miles on it
I've been experiencing all above problems mentioned in this thread
my car is still in ford after a week of trying different things egr(third in 3 years) map(2 in 3 years) (air mass sensors only 1) reprogramming update (countless times) etc.
its showing no faults on ecu but drives like a pig and very heavy on fuel
its seems to go into limp mode daily
was wondering if there were any real protests to manufacture for compensation or real repair,
or do I just get rid and lose thousands ?
any good sound advice would be appreciated

a very broke
Richard - Bristol

Anyone having problems with the C-max transmission please visit my Facebook page Ford Focus C-max 1.6 TDCI CVT premature gearbox failure & click like & post your problem trying to get Ford to take action on this issue that has been around for years!!!!!
ferguswalker
Ford C-Max 1.6 dci manual 54 plate. Having same "hunting"/"power loss" problems experienced by many in this forum topic - is there no hope for us? Been in the local Ford garage but as you might expect, the problem persists. What is the prognosis? Any one had success with changing the chip and at what cost? Has Ford ever acknowledged the problem?
Dental angel
Same problems.
I have an 04 plate - problems from the start I bought the car from a ford dealer I was looking to buy an 1.8 didn't mind what type , came across the 04 c-max took for a test drive seemed ok paid deposit should have received car a week later but still in garage , I was informed the car when I bought it was put straight on the forecourt as they didn't have enough stock and not checked, I thought well at least it was having a proper check, 3 weeks later I received the log book - checking through this the 04 c-max a was actually a 2.0 tdci I immediately complained to the salesman that the paper work he had given me was for a 1.8 but I was actually sold a 2.0 tdci , I asked where I stood in relation to getting my money back he replied it would be difficult !
I have had the car for just over 2 years it has now occured the same faults it is going into limp mode. I have called the AA out 4 times this year , the last time it went into limp mode the complete loss of ignition no power doesn't even turn over.
I need some help and advise if I cut my losses I've been told I would only receive trade in about £800 !
leon samual
Talking to ford rep as power loss seems to be common faut. He said its mostly fuel filters. Try that first
