Hi All,I have an odd vibration problem with my A3 2.0T 8P 2005 S-Line. It is very hard to describe but I would say it's worse at around 50-70mph and other than these speeds, very little vibration. The vibrations are felt throughout the car and the steering wheel.I've tried having all wheels aligned and calibrated to no avail.Getting very frustrated and any ideas or input is much appreciated.ThanksScott
