Classic Cayenne plugged drains. It’s the spliced wires under drivers and passengers carpet. Near dead pedal. Now thinking it could be low on trans fluid. If I rev it up in neutral and drop it into reverse it will at least bump backwards a bit (I know cringy to think about). Seems like trans wants to do its job but something is telling it not to engage. Thank you guys for your responses you’re like celebrities to me. I have used your advice from many other threads.

lol I should pick and choose my words carefully. I was referring more to picking up a Porsche specific scan tool (along with the fact that I am new to the whole Porsche diagnostic game). Just curious is it possible this “limp mode” would not allow a gear to engage. Does not sound likely. Another possible route would be the transfer case stuck in Neutral/not functioning normally. Or the shift cable not fully engaging a gear. In any case I understand that without a proper scan this is just one big guessing game.

Still thinking it is an electrical issue! It seems like the psm ecm are not allowing the trans into gear. Will definitely be picking up a Durametric or piwis. Figured I would put it out there to see if anyone else has experienced similar things or has any ideas on things to check or try.

Looks like you should change the oil and take her for a long hot drive. Looks like the classic issues of not getting up to temp.

Problem Starting

Try checking for rear battery in spare tire well. Your car may or may not have. -
Hi there, I just picked up my new Cayenne. It starts and will go into gear (with a clunk). reverse (just revs and hits limiter at 4500) neutral (creeps forward) drive (will move forward but you must rev it up to get it to move at all, then after a few feet it slams to a stop) PSM light on, CEL on. battery is decent have a tender on it during diag. codes: speed sensor A intermittent/too high p0503, ambient and oil temp too high/intermittent. will go into 4wd no change on how trans acts. i have peeled up the carpets and fixed a handful of corroded wires. almost feels as if parking brake is on or the car is not actually in gear. Jacked up rear end wheels spin freely in gear (not park) and out of gear any ideas?
