I have a 2001 Tdi 130 which is shaking when I'm sitting in traffic (goes away when I increase the revs and also when I turn the steering wheel slightly) The needle on the rev counter sits perfectly level. I have run diagnostics and found no problem. Took the car to my local mechanic and he told me it was a dirty fuel filter - fuel filter replaced and system flushed, but the problem still exists. Does anyone have any ideas? Could it be worn engine mounts?
