I'm posting out of frustration. An 05 Passat TDI, automatic. Vibration at idle in gear has been growing over one year in spite of having the Balance shaft upgrade(Oilhammer) with motor mounts replaced, and more recently putting in axle replacements(Raxles) without improvement. It's been cold, so I haven't gone looking for the transmission mounts yet.

Could it be them? It sounds like a rare problem, or no?

It gets better when I shift to neutral, but replacing the axles didn't improve it. I did that just two weeks ago. Raxles has a good reputation, and I followed the very good how-to you have posted.

If I get under the car (on jack stands) and watch it while running, and have someone shift to D and hold the brake, what are the odds of seeing something that explains this?

One more thought about this: When the cover is off, you look at the engine running. Your helper shifts to R, then N, then D. To me it looks like the engine moves a lot, nose up for D, nose down for R, more than I have noticed in other(gasser) cars. Does VW have a spec for this amount? It seems that if this amount of movement is large, there is more potetntial for vibration.
