I bought an A4 Avant (B8, 65 plate) from a main dealer in June 2016. It had 10,000 miles on the clock. It started juddering at about 12000 miles, and ended up needing a new DMF and clutch - all done under warranty. The juddering started again a few weeks ago, so I took it back to my local main dealer. They couldn't find a problem on a (very short) test drive, but eventually agreed to take the gearbox out. I've been told that the clutch has burned out, and has to be replaced, but not under warranty this time. The manufacturer's warranty runs to September this year. I know they class a clutch as a wear and tear part, but I've not had a clutch problem in 24 years of driving, and this car has needed 2 clutches in 34000 miles. I'm suspicious that there's an underlying mechanical problem they either don't want to tell me about, or don't want to look for. Any suggestions on where to go from here, and how worried to be about the car? Thanks.
