Hello everybody, I’m about to buy a Porsche Cayenne Turbo Bj. 2004. I looked at the car and I noticed that I can’t drive the chassis up and down. On the display it’s not possible to regulate. I approached the seller and he said it was related to the big wheels (20″. Can someone please tell me if the chassis is really locked or how I can test the chassis differently. If the regulation is blocked i st, how can I unlock them for testing?? Thank you in advance
