The 8-valve 1.6 TDCI which was used on the Focus MK3 is completely different from the old 16-valve 1.6 TDCI which was used on the Focus MK2/MK2.5. This topic originally referred to the old infamous 16-valve 1.6 TDCI which was known to have many problems.

Most of the known problems of the old 16-valve version were solved in the newer 8-valve version of the 1.6 TDCI. The 8-valve version however turned out to have different problems. For example bad fuel injectors (needing to change all 4 is not uncommon), defective clutches / defective 6-speed gearboxes (caused by low RPM and high torque) and problems with the emission control system.

The 95 and 105 HP versions do have an additional fuel injector and glowplug inside the DPF to increase the exhaust temperature during regeneration. Failure of this system is quite common and results in a blocked DPF. The 115 HP version does not have this emission control system which makes it much more reliable than the 95 and 105 HP versions.

Very interesting comments. I have the DV 6 1.6 TDCI 115HP with 130,000 on the clock. What should I be looking out for? Or looking to change?

Is your signature correct? i.e. your car is a 2013 plate, if so your engine isn't the DV6 version (the 16 valve version out of the MK2 Focus, it'll be the newer 8 valve version).  As is usually the case @JW1982 summed up "your" engine's potential weaknesses nicely on page 1 of the thread.

The 8v is still a DV6 engine block which probably explains the confusion...

DV6A & DV6B are the older 16v.  DV6C & DV6D are the later 8v.

Just didn't want him to get a long list of potential issues with the "older" version of the engine, maybe they should have called DV6C DV7 instead. 😁

 

As I've said it before, I think it's a real pity that even the newer engine/drivetrain combination had issues because I found the engine to be fairly quiet (relative to a 1.8 TDCi) 🤣 and pretty flexible in real world driving.  But regardless of how "well/nice" an engine goes there's nothing worse that knowing "your" car has multiple confirmed significant weaknesses/vulnerabilities and in your mind (once you find out about them) you're just waiting for one of them to rear their ugly head and cost ££££ to fix.

Oh yeah, I wasn't trying to correct you, just trying to avoid any further confusion lol!  A different name definitely would have helped, but DV7 naming wouldn't work, the 6 relates to the 1600cc capacity...despite it actually only being 1560cc!  

 

Every engine has it's massive potential faults tbf, that seems to be getting worse they newer you go though!  I think it's worse for those of us that have a bit of car knowledge and spend time on forums...people that don't care don't worry about it until something actually breaks!

I'll go for DV5.6 then! 😁

 

I think most of us would agree that as more technology is mandated/forced on manufacturers to meet the latest emissions standards, it seems to largely be creating an ever increasing list of items that can and often will go wrong.

 

Look at the situation with Volvo for example, they launch their "own" 4 cylinder diesel engine 4-5 years ago (VEA range) with a standardised block etc (all sensible so far) but rather than pay extra to design/integrate "Adblue" to be able  to meet the emissions standards at the time, they took the blunt force (cheaper/simpler) approach and just relied on the EGR to do some serious heavy lifting.  The EGR is really aggressively cooled which caused moisture inside the valve, it also has a REALLY restrictive path so I reckon you'll be able to guess where this story is going!  Lo and behold, from not long after the engine was introduced, owners have been complaining about the EGR and EGR cooler failing which has ultimately led to Volvo being forced to launch the recent recall regarding the plastic inlet manifold.

 

The not very funny thing about this situation is Volvo have confirmed that they're still working on a solution, so the recall leaves all affected owners in limbo whilst Volvo make up their mind as to how they'll address the issue.  Not great when they've known about the weakness pretty much from launch and maybe before launch.

That's interesting, I hadn't heard about the Volvo issue.  It's very similar to the VW emmisions fix though.

Basically they knew the EGRs weren't up to the job and didn't want to use adblu so just used a bit of cheat software that overworked the EGR when on a test rig (front wheels moving, rears stationary).  Once they were found out, the emmisions 'fix' mapped the EGR to be constantly overworked, which not only ruins the EGR valve much more quickly, it fills the DPF quicker requiring more regens too.

I'm constantly worried about the EGR on the Golf because of that...

Yeah, the Volvo issue was less about deception (it would appear) and more about simple £££/time to market.  The said thing is the engines are really efficient AND can deliver good performance, I only really know about it because I've started to research what my next car might be and outside of a MK4.5 2.2 TDCi Mondy Tit X Sport, I've been looking at V40, S60 and V60 (2014 onwards) as they have much nicer interiors compared to the equivalent Ford, as well as an excellent mix of performance/efficiency.

I really like the V40 myself, more refined better looking and better built than the Focus, less boring than the Golf...the only thing that puts me off the ones in my budget is they're all DV6s lol!!

According to Etis I have the 16L Duratorq CR TC (115 PS) DV6. 

 

So apart from bad injectors it's not a bad engine. Is there symptoms I can look out for injectors?

Misfiring, jerking, just generally driving like rubbish really.  The clutch & gearbox are pretty poor quality as well on those, the clutch has probably already been replaced once on that mileage.  But apart from that they're fairly reliable engine-wise, they don't have the carbon deposit & turbo issues of the old 16v engine, and the cDPF fitted to them seems to work well, although at 130k that's another thing that might be getting towards the end of it's life.

Ah, I did have a bit if a strange judder when accelerating. I say strange because it didn't do it when accelerating hard or in low gears. I changed all three engine mounts and thought the judder was reduced but not completely gone. I changed the fuel filter and that seems to have stopped it. As for the clutch, I have the dreaded groan, so that might be the next job! 

Ford focus 2007 1.6 tdci 170000mls .. dpf and egr are not deleted!! Everything is ok!!

Hi. my son has left his car on my drive for me to sell. Its a 2007 1.6 Zetec Auto with 209730 miles. It has only had 2 owners my brother in law had it as a company car until 2010 and covered 156000 since then my wife has owned it and my son has used it covering only 1k in the last year. It sailed through the MOT with only a CV boot split so pretty good.  Sadly it needs to go so someone is going to get a handy run about for a few hundred pounds.  

Not sure if this mileage is a record but must be up there (never used as a taxi!! other than to run kids to sport etc)

 

Mines not the dpf version and I've just started to suffer with 15+ fault codes and limp mode.

She's on 193,000.

Egr failed earlier this year so deleted that.

If I can get to the bottom of these codes (possible instrument cluster) im told then im sure she will plod on for a while yet easily above 200k.

just bought an 2011 plate mk3 with 175000 over the phone collect Monday here's hoping alls well

 

How much did you pay for it. I’m looking at one today ? 

Looking at a 1.6TDCI Fiesta Van (61 plate) 210,000 miles, drove it for an hour, MWay, A and B roads and traffic, went lovely, service history. Worth a punt ?

My 1.6 TDCi (10 reg) has done 144,350 miles and is running well at present, though it has a small oil leak and the yellow engine malfunction light has been on constantly for a year (diagnostics say it's the oxygen indicator according to my local small garage). I've had ths car since the 31,300 miles mark. Before that I had a Focus 1.8 TDCi which I sold at about 147,500 miles, and before that a Focus Y-reg TDDi which I sold at 142k. All three have been generally reliable, and are all I have driven since 2003, although I've had to replace the TDCi's alternator and clutch recently and the TDDi had a niggle regarding the glow plug towards the end (light came on and engine would slowly lose power, but could be fixed temporarily by stopping for 5 mins) plus a leaky rear window seal.

Hi, how many miles do you think you can get out of a ford fiesta 2010 1.6 tdci. Mines on 189000 & it's still running just as good as it was when I bought it 11 yrs ago I've changed the belts twice on it & I keep up to date with getting it serviced every 12 months & so far it's doing an excellent job by doing that. I've got a garage that I've been going to since I've been driving & they are really good mechanics & always tell me I've got a really good car & to keep it going as long as I can. I really trust this mechanic as he's a friend also. I've had the car 11 yrs & only had 2 mot failures. Also original clutch lasted 177000 miles had it replaced last June.

Thanks Craig

I had a berlingo for work with the same engine ( or so I believe ? ). Anyway 240000 miles and it drove fantastic, I would say it went better than our C Max with 125000 on it. I put it down to spending most of its daily life going up and down motorways and because of that there was no reason to have the DPF or EGR deleted or any ***** faults
