After a lengthy 8 months chasing round trying to find out what is wrong with it I've had the coils changed, an engine flush, sensors checked, compression tests, the lot! Let us know the results and we can go from there! Next I am going to check that the injectors are squirting fuel by removing the rail and placing each injector in a bottle as if no 3 cyl is misfiring I would expect to see a slightly wet plug but that is dry, I understand the ecu can shut off an injector but thought when the code is cleared and engine initially running the injector would squirt a little fuel. All good there. Do you know many people who've written to VW about the problem? I am running out of ideas so any help is greatly appreciated. Its an shame as its been a solid car up to this point Thanks. Cheers, Martin. Top Contributors this Month View All.

In we bought a new Fiesta and a week or so after the ONE year warranty ran out, it developed a valve guide issue which meant it was burning a lot of oil, Ford washed their hands of it with miles on the clock so I had to pull the head myself, thankfully a 70's Ford Kent 1.

Yes it is a common problem but VW blame the fuel in the UK saying it is poor quality and citing that this does not happen anywhere near as much in mainland Europe, which is true, it doesn't AND our fuel is poor quality in comparison, especially supermarket bottom of the barrel scrapings. All good there. I would be grateful for any suggestions? Don't know what to do next??? I am running out of ideas so any help is greatly appreciated.
