My 2015 jetta tdi has excessive vibration in the cabin at idle in drive with my foot on the brake. It is worse when warmed up. In park/neutral it idles smoothly and nothing is felt in the cabin. My dealer just tells me "it's normal, tdi's vibrate a lot". He has no tdi's in stock to compare. My 2009 that I drove for 240000 miles was always smooth in the cabin when idling in drive with the brake applied. I drove a 2015 Golf TDI yesterday at a used car lot and it was smooth like it should be also. One thing with this 2015 is when I let off the brake, it responds pretty much immediately with movement where as my 09 had quite a delay. To my knowledge, when in drive and stopped with foot on the brake, first gear is engaged and some pressure is applied to the first gear clutch to preload it to the "bite" point. When I shift between N and D, the tach needle does not move one bit, stays steady at 800, so it can't be much preload or it would drag down rpm a little. I have read many threads on motor mounts but it is perfect in P or N and in D the motor sees no load because the tach doesn't budge, so I'm thinking no way it's the mounts. Anyone know if this preload pressure on clutch can be adjusted with vagcom or even measured so I can compare with other people's? This vibration is not normal, it's more like a deep resonating sound shaking the whole cabin that is only present when stopped in gear. As soon as brake is released it goes away and the car moves. It is not one of the many rattles that these cars have, I've corrected some of those. There shouldn't be much difference between P and D with foot on the brake and there is.
