Hi, I have a few week old A4 3.2 Avant S-Line - Occasionally when reverse is selected the car will over rev (as high as 4K rpm) before beginning to move, which is very disconcerting.

If it were a manual I would suggest that the clutch is slipping (badly). I have searched the forum and the net in general and cannot find any thing similar on such a new car.

Audi have had the car back once to investigate the issue but could not replicate the problem (undoubtedly they did not test long enough). The issue is actually very worrying as we are fearful that the full power of the engine could kick in at any time which could be very dangerous when parking etc so any comments or advice would be gratefully received.

Thanks.
