I have an A5 sportback quattro s-line 2.0tsfi auto (DSG). When I first collected the car the gearchanging was smooth and silky and imperceptable. About a month into driving this car and the gearchanging is snatchy and unpredictable. Not all the time though. My Audi dealer says and I quote "this is performing exactly as this car sould be". Also when cruising it kind of does this rythmic surging and the rev counter flips up and down just a little. Also sometimes it sort of crunches into gear when going from a standing stop. This car has 5000 miles on the clock and has been back to Audi 3 times but I think they think I am a mad woman but I am not. I have owned many nice cars over the years so it's not that I am just not used to it. I know my own car and there is something not quite right with this one... Oh and also I have never in all my years driving had a car throw off so much brake dust as this one and it's sort of greasy.... any techy guys out there to help me ????? For nearly £40k I am unimpressed :mad:
