Hi,

Could someone give me some advice on how to go about checking the fault on my Mondeo MK3 2.0 TDCI year 2006? When I floor the accelerator even beyond 3000RPM when overtaking it goes into limp mode. When you turn the ignition off and restart, everything works well again. I've changed the fuel filter but still the same. Sometimes it happens and other times it doesn't. The car went berserk once, engine went revving with loads of smoke and I had to turn the ignition off. Then came all this problem few days later. Could it be the glow plugs?

Please advise on what to do

Thanks!

Welcome Along!

check the fuel filter hasn't been put in back to front, and when you changed the filter, did you replace the housing seals too? sounds like it could be air in the fuel lines to one extent,

The issue with going berserk, sounds more like the TPS hadnt returned, so it thought you had your foot down through the floor, or perhaps the pedal got stuck. wont be anything to do with the glow plugs specifically...

Hi,

Thank you for your suggestions. No o-rings were changed when I changed the filter. I think you may have a point here with regards to air in the system. I will go about checking it today.

Thank you and will keep you informed on the outcome!

Many thanks.

Is your mondeo the same as mine, it uses a canister fuel filter? There isn't really much to go wrong with them to be honest.

You will need to get the codes read otherwise you are just having a stab in the dark.

Hi,

Yeah mate, your Mondeo is the same as mine. I will change the fuel filter one more time and check the o-rings as suggested by jeebowhite and see how it goes. If it still happens then I suppose I'll have to get the codes read.Couldn't get around to it just now as it was blithering cold. Will keep you guys informed.

Cheers

Hi, I changed the fuel filter to a genuine one. I checked the o-ring, there was only one and it seemed ok. After I put in the new filter, I revved the engine for a good 1 minute hoping any trapped air would dispserse. Took the car down the motorway, thrashed the bugger and it was top notch. Fingers crossed it will remain this way. Will keep you guys posted. Cheers

The glow plugs are only used to start the engine, and should have no effect once the engine is warmed up

The variable vanes on the turbo can coke up, which can cause exessive boost pressure as the VNT (variable nozzle turbo) controls the boost via the electronic or pnumatic actuator,the exessive boost pressure is liable to occur at high revs/ load and can trigger limp home mode. "thrashing" it can help to clear the coking up a bit and loosen off the vanes

The other thing that can cause similar symptoms is the EGR valve, this can be intermittent as well as the valve can stick then un-sieze

Its a good idea to get your falt codes read/ invest in a code reader, without the codes its just guessing really

If it is reduced fuel pressure causing the EML/ limp home mode the new filter will have sorted it, generally a genuine/ quality filter flows fuel better than a cheap pattern one

On a Euro 4 Mondeo mk3 often the power can drop off above 3.5k/ or peak power is at 3.5k, if this is the case it means there is no point in revving it past this and you may accelerate faster and get a better consumption if you change up at 3.5k when you are "in a hurry" rather than revving it out all the way to the redline, untill you are in top (on an autobann - of course!) it seems counter- intuative and redlining it may give the illusion of going/ accelerating faster - but some of us have even timed these things (depends on the exact engine/ power curve)

Hello, the car is still running top notch. What you have mentioned makes a lot of sense and I'm thinking of buying a fault code reader - any particular one could you recommend? There are so many on eBay and Amazon that I don't know which one to go for.

Is this the one I should be going for?

 

Thank you

You may have an OBD1 compatible car,(not OBD2) OBD2 did not become manditory on diesels untill 2004,(petrol = 2000) the plug/ device will phisically plug in but it may not be electronically compatible/ may not "pick up" the codes 

 

The only code readers i know work with pre 2004 cars are the F-super and the Ford- compatible superchips bluefin BF-005T

 

Thats if your Mondeo is 2001 as in your profile, if its 2006 as in your post, any Ford- compatible (there are 4 different widly-used protocols) OBD11 reader will be ok (even if your exact car is not listed if it lists a lot of Fords its probably OK on post 2004 diesels and post 2000 petrol cars)

Hello mate, the Maxiscan Diagnostic Scanner OBD2 MS300 says "NO CODES" on the screen when I plugged it in. The engine was running and even not running shows NO CODES. Should the management engine light be on before it can give us any codes because my car doesn't show any warning lights.

 

Please inform soon.

 

Thank you

Cheers

Im not familiar with the device, ive looked at it online and it claims to have the Ford protocols, but it may have to be setup/ programmed for these protocols and "generic OBD2" may be the default setting, you will just have to read through the instructions

 

there is a CD rom with the scanner, that may just be the PDF manual or it might have the ford protocols on  

 

Update - you put the cd rom in your pc - and the programme tells you what the fault codes (dtc) mean

 

is the machine lighting up? - make sure its plugged in fully - you may have to push the socket and plug together because of the way it is made

 

it should do something different when you turn the ignition off/ on/ start

Hi Basil

I too had a limp mode problem when accelerating. The red 'cog' engine stop lamp would light up rather than the amber engine management light. My code reader is unable to read the faults associated with the red 'cog' only the EML when illuminated.

Worth going to the garage to read the cached fault code/s then tackling the cause if necessary. The diagnosis on mine was EGR valve which I've subsequently blanked off.

Best of luck
