There is no fault. I have used Porsche specific scanner and my own diagnostic tool. There used to be a P708 fault but I changed the multi function switch and that runs fine.
The car runs fine in tip and auto, just the D light is still blinking.
I have checked live data from my diag tool, and whilst driving 70mph on the motorway my tiptronic gearbox is showing 196F temperature. Is this correct? Does anyone know the operating temperatures for these gearboxes.
My thoughts are 1) Gearbox temp sensor is faulty (although no codes)
2) ATF fluid is low.
Anyone can help?? Kindly don't refer me to go to an OPC to put a PST2 tester on the car.
