I am in my third one now, all ran from new up to approx 160000kms. Bar some really crappy dealer service, I have no complaints and had only one issue, a turbo failure which was replaced under warranty 2 years in. Happened as I was heading down the M6 in the UK and Audi orgainsed to have it replaced in the London the next day, even collected the car from the hotel and left me a loaner.
