Front differential
 

Good day all

Purchased Cayenne S, 2004. Great car. Couple of questions:

There is a noise at front, my experience tells me it is ball bearings of the front differential. However, I can't test it. As soon as I raise the car off the ground on lift, and have one person to drive the car, it blocks the wheels. Seems like ASR/ESP or whatever the auto stabilizing system is called, functions.

THere is a nob, called PSM. Even when I switch it off, still blocks.

So:
- how do I turn the system off, to be able to run the car off-ground
- what other noise it can be, except the differential?


Thanks a head

Guys,

no one knows how to disable stability system fully?

I cannot diagnose my car without running it on the stand.....
