I just bought a Audi q3 140 TDI with the manual gearbox. The first two days everything was perfect. I started then feeling a vibration on the clutch pedal that is increasing from then. After 30 minutes in town today I dearly leave my foot on the clutch and I prefer to pass quickly in neutral (death point) to rest my left foot! I left my car at the service for 5 days and they gave my car back saying that everything is normal and that they don't see any problem.... I asked to drive an other Q3 TDI and the difference was great : No annoying vibration, the clutch pedal was quiet lighter and overall I felt less vibrations. The technician agreed that there is a significant difference between the 2 cars, but he still can't see how he could fix my car ....Today I hear a slight vibration on the dashboard behind the steering wheel when I accelerate from the first gear to the 2d, I have a feeling that the brake pedal is shaking very slightly I even have the impression that the gears don't change as smoothly as in the first days .... I must say that I didn't expect that from Audi.I am really disappointed by this car, does anybody else have these problems ? If yes, is there any solution to fix them?
