rough idle vibration resolved - 2004cs @75k

Recommended Posts

Replaced all of the engine mounts - lowers, dogbone plus the transmission mount.  There is still a small idle drop when coming to a stop, but it's no longer transmitted through the car.  


completely different car.

Wish I did it earlier - the car is vibration free.


With all porsche parts and independent shop labor, the cost was 900-1000 USD.


The labor was 5 hours.


Good luck.  If I had a cayenne with vibration when I started the car, I'd change the mounts.  Might be worth starting with the dog bone mount first - its the least expensive one to do.  I did the dog bone, the two lowers and the transmission mount - vibration is gone.

Engine mounts on the Turbo need engine out to change. I had perfect access to my drivers side engine mount when I pulled the turbo, but there was not enough clearance to get the mount out the subframe - the built in threaded bolt prevented it from being removed.
