Hi all, We have recently purchased a 2010 Q5, with full main dealer history and 85k miles. It is the 2.0T FSI engine, and had the oil consumption work done last year under warranty from Audi. Perfect we thought. However, we have recently noticed the revs surge up and down when reversing. My wife said that they went very high when she tried to reverse up a hill the other day. All forward gears seem fine. Any ideas? I’m hoping this isn’t going to need a new mechatronic unit and clutch, however I fear this is what you are all going to tell me! Do you think Audi will step in? The gearbox oil was changed at 35k and 65k by Audi.
