Thanks. I'll figure out which sensor it is, but a question I have...did you (or your mechanic) access the sensors from underneath the car or from the engine compartment? And if from underneath (my guess), did you have to remove some of the "ground effects" plastics? I would thing you would. I'll probably tackle it myself. BTW, FYI, you can get your OBD II codes tested for free from your local Autozone store. They do the test and give you the fault codes, and then you have to figure it out from there. I'm counting on a forum or google search to get that answer. Heck of a lot better deal than $100.00 per hour for diagnostics at the Porsche dealer. I look forward to hearing from you.
