When accelerating hard it seems a little hesitant or jerky moreso when warmed up. Any comments or knowledge on this issue welcomed (or not if it serious).
Might be your many things, but Transfer Box oil low/contaminated with water is a potential issue on Cayennes. Easy fix and oil change prevents this/a big bill.
Just to let you know EGTE you were spot on with transfer box. Had it replaced last week. Didn't know when I got the car (not from a Porsche main dealer) that it had been purchased originally with 5 years extended warranty on it!!! The bill would have been 3k. Much relieved.
