I'll take a quick stab at this since you haven't had a response. Since this is a recent purchase and you don't know the age of the battery, I would consider starting there. Sometimes a weak battery causes different sensors throughout the vehicle to throw codes simply due to communication problems. I know it sounds kind of crazy, but I've seen it work.

Well, after 3 days of stuttering starts until it turns off the AWD, and all the lights come on...I went to the doctor today...when I left, the car started right up, no lights, no stuttering...ran normal! Go figure.

BTW...thanks for replying!

I believe you already posted this? And I answered it. Mine did the same about a week ago. Saturday it got a new RR wheel sensor. ALL those codes are caused by the PSM not knowing the speed of that wheel.

DO NOT ERASE THE CODES - take it to Porsche. It's covered under an extended 10-year/100,000 mile warranty. Unfortunately mine was no longer covered, but a new wheel speed sensor from eBay(China) was only about $13, so I bought several and keep the spare one in the car.

Thank you very much!
