Audi A6 1.9tdi 2002 130 BHP AWX I have just cleaned up my EGR valve as it was minging. The plastic plunger that is connected has a diaphragm. Does anybody know if you can buy this(whole plastic bit including diaphragm) or do you have to buy a complete EGR valve. Tom

The has now done 120k. I do about 40k per year. I buy my fuel at Esso proper legit fuel. It looks ok inside the air filter housing. I've also read that if you blank of the egr valve then you will get oil from the sump dragged into the air intake. I just don't want to do all this for it to happen again. Wish I had just replaced the egr the first time. Thanks for your response. Think I left a black cloud over the stadium of light! It hasn't cleared yet! Tom

I have had some problems with my 2002 Audi A6 1.9tdi lately. About 6 months ago it started belching out a lot of smoke and the turbo stopped working. I got a new turbo fitted my my local diesel injection centre. They said the problem was caused by the EGR valve and suggested blanking it off. This was done and it ran a lot better for a while and now the turbo has failed again.I have done some research and apparantly if you blank off the egr valve the turbo will break due to the high operating temeperatures. Thank you Sunderland Diesel Injection Centre for blanking mine off. Anyway my plan is to replace the EGR valve the Turbo (again) the oil supply pipe to the turbo and gaskets and nuts etc. I am also going to take off the inlet manifold and clean it out as it is full of oil.The pipe that comes from the intercooler to the egr valve is also quite messy so I will clean this as well. Is there anything else I should do at the same time or is there something else which could have caused the problem? Hope some of you have some ideas? Regards Tom Cram
