Step motor
My (early build) 06 S w/ 38K has been at the dealer all week for a host of issues -- mostly repeats. At this service and previous one a couple of months ago they have really gone the extra mile to try to get to the bottom of a few nagging intermittent problems.
They replaced the step motor in an attempt to eliminate an occasional dash warning that occurs (sometimes) after I have returned the car from the first reduction. But I also get the 25mph clunk/ thump downshift occasionally -- they think it is related - I have my doubts.
Can someone explain the function of the step motor

Drifting
When the stepper motor fails, the center diff does not disengage properly and causes jerky motion in slow speed tight turns and fast tire wear sometimes.
Of course Porsche doesn't use VW/AUDI parts (According to dealers around me) so you wouldn't have this problem. This was a common problem on early touaregs.

There is a -C part number currently out. Older ones were -A. It's the same motor between the Treg and Cayenne, so I'd find one for a treg as they're cheaper.
This is the manufacturer PN, not the Porsche PN. AFAIK - there aren't any updates to the motor after this.
