Right, I've spoken to Audi today and they said that the cambelt change criteria for my 3.0 v6 is 75k or 5 years on post 2004 cars. So as mine is a 2002 it wouldn't come up on their service schedule for a belt change until 75k. They didn't know why it was 2004 onwards as surely mine is the same engine spec, or did they change the cambelt parts??? Mine is on 29k so not sure what to do. Has anyone else heard of this?
