You can feel most of it directly through the accelerator pedal. From what I can determine the vibration is ONLY coming from the driver's side wheel area. There is no real noise. The transmission shifts smooth, but once the vibration starts it will down shift a little rough, like it is catching on something. Once it starts, it gets to a certain degree of vibration and stays there, it does not seem to get worse. I do not believe it is the transmission itself, but I do not know a lot about these DSG trannys, so I guess it is possible. The problem seems to reside someplace in between where the transmission sends power to the wheel and the wheel itself. Does this particular problem seem to be something you might have heard from before?
