Exclamation Cayenne Turbo Vibration when Stopping!!! Help

Hello all
I'm reaching our for solutions
I have a 2004 Porsche Cayenne Turbo and my issue is, when coming to a stop of any kind the car vibrates and idle dips ever so slightly. I have changed out the spark plugs and coils, Drive Belt, and the Secondary air injection system P0491 code threw at me just recently. I'm at a loss at this point...
When coming to a stop if I put it into neutral it doesn't vibrate. When it's cold it's worse.

I have the same issue. When my 2006 Cayenne S about to come to a stop, I feel a little vibration. I don't feel it when I put the car into neutral. The front brakes (pads and rotors), torque strut and lower control arms have been changed out. I am wondering if the issue is motor or trans mount? I haven't noticed a drop in idle and I have no codes.

Same issue with my 2006 Cayenne S. I guess "they all do that". I've searched various forums over the years. No definitive solution has ever been posted. The most common hypothesis are:
1) Cracked coils, even those that don't throw a code.
2) Vacuum leak in air-oil separator cap. Replaced mine, and it did not solve my problem.
3) Leaking motor mount. Not easy to replace.
