07 S sometimes goes into limp mode even after replacing throttle body and complete accelerator assembly (both new parts). No error code. Can be fixed by switching off and restarting. Any clues? Sorry if this is a duplicate but I can’t find a relevant thread.
Hello all, I have been lurking around here for almost 2 years. I have a 2006 Cayenne S with automatic transmission with about 70,000 miles. This morning I went to drive it to the car wash. When I went to accelerate onto the autobahn the engine acted as if it were in limp mode. There was no power under load above 3,500 RPM. In neutral the engine will not rev past 4200 RPM. Here is what it is not doing or has been replaced - It starts and idles fine. - plugs and coils replaced last year less than 10 thousand miles ago. - I do not have a check engine light on. I am thinking: 1. MAF sensors (looks like a special tool required for replacement). 2. Throttle position sensor 3. Fuel Filters 4. Fuel Pumps 5. Or another sensor related to fuel pressure or fuel regulation/delivery system. Does anyone have any trouble shooting tips or advice before I give up and take it to the dealer?
