It ruined the flywheel because it was driven in that state repeatedly.

Most emissions control equipment isn’t even active under 18*C ambient and research published yesterday suggests that whole life CO2 output is actually higher than equivalent petrol engine. In my opinion the latest models are most offensive from a smell perspective.

When the chain “stretched”, in my case the car suffered massive and sudden momentary power loss under load in the mid range. No warning lights. But the diagnostics was very quick, there is a defined procedure of course and the cam lock tool doesn’t fit in at TDC because the cam is basically off by a degree or whatever. CTHE, 30k-ish, 2014. but anyway, what is meant by a chain stretching? From what I have read it is the pins wearing that makes the chain appear to stretch, and that can only be due to inadequate quality components or lack of lubrication. It’s worth noting that VAG has extensive history with the former via the 1.2TSi and the lower powered twin chargers.

I was lucky, the CTHE I had never needed a single drop of oil. CO2 isn't the issue; for me cycling in London every day I can choose not to smoke, but I cannot choose not to breath the diesel fumes. The odd thing is that the newest cars and vans are the worst, that awful dry choking quality to air that just lingers even when it's windy. And of course, it turns out this is massively poisonous as well as unpleasant. So, good riddance to them as far as I'm concerned. VW group has seemingly gotten away with their myth around diesel being in any way 'clean' notwithstanding the engineering of test results. The whole issue has certainly resulted in VAG vehicles not being on my shopping list this time around as I find the company to be disingenuous around their brand promise, and also of course the test results and many examples of poor quality engineering.

The best approach to cleaning them up is to scrap it and buy something not powered by the devils blood.

I hope so.

Apparently DPF will be tested in the MOT from April next year (currently a simple visual check). http://alderleyautos.co.uk/mot-northampton/mot-to-change-in-2018/

2.1 bar I presume at 6,000 rpm

Frankly that call from them is awful. No one would make that Up three times, inconveniencing themselves with garage time in the process. In my view you are owed a writen apology and financial compensation for your time due to clearly inadequent investigative works earlier AND having reported to you work was done that wasn't. Please name the dealer here too

FWIW I suspect there will be a significant strengthening of diesel MOT tests. pre 2009 cars are now being targeted for scrapage, those are not old vehicles really, and have a bunch of emissions control usually, in some cases including DPF.

Yes if it's worn right down the rivets can make contact leaving scoring, meaning the flywheel has to be machined (skimmed) as part of the job.

If the friction material gets completely worm through the metal on metal will also ruin the flywheel.

I'd suggest that you will need to find "the right" buyer for this. There are undoubtedly buyers that will be interested in the works performed. For me the car would be worth book price, less the cost of putting the proper rear axle back in it and the EGR valve, since that may become a future MOT failure. any prospective buyer would presumably have to weigh up just getting a VRS if they are interested in those parts of it.

If engine speed increases without any increase in car speed then absolutely the clutch is slipping and will need replacing.

Had a chain on 2014 CTHE changed just over three years 32k, no sound or lumpiness other than normal at startup, just occasional lumpiness on the road and some pinking at low rpm.

It's under warranty but I can't be bothered TBH, more time off work etc and I've only got it for another month. Just posted for info for everyone else really in case there is a pattern,

Since mine had the pressure regulator update it's been a bit temperamental: unable to creep up hills - clutch eventually disengages and engine revs freely occasionally misses second under full throttle (again engine revs freely) near stall situation due to slow de-clutch in emergency brake situation none of those issues have been present before the update.

Just amazes me how we all fell for stinking sooty diesels being in any way environmentally friendly - me included.

Because the reality is that those test achieved emissions bear little resemblance to real world conditions. A lot of the emissions control stuff is turned off under 18*C for a start.

Sure it's not pinking?

I think the blue light is just there to say "go easy" basically. FWIW I generally let it idle for 10s to give the oil chance to circulate but the handbook actually says just drive off right away.

The reality is that diesel is finished, and government could turn them all off for good with an MOT NOX test when the time comes.

Ungood!! Such practice greatly increases engine wear since byproducts of the rich combustion when cold include some acids. It's also not very environmentally conscious.

MOT may well only measure particulate today, however this may well change in the future given the sheer toxicity of the NOX issue. If the car hadn't had the update whilst it was offered, the car could become unroadworthy. Just my 2p obviously.
