Hi Porsche friends,
had my car taken in for the PDK clutch oil service (6 year interval). My car is from 2009 so it is a bit late. I have had the car since summer last year.
The service was done at an independent specialist with the right OBD tool, official instructions, maintenance parts etc: Oil drain and top up between indicated engine temp, then follow OBD tool instructions and let the automated calibration procedure run.
The engine speed is now unsteady under load when accelerating approaching 2000rpm. Engine speed trace would look like a jigsaw on an oscilloscope. The car runs fine at steady state and in general above 2000rpm. To be honest it is a minor instability but definitely enough to notice. It s clearly visible on the needle and also from the engine noise at any vehicle speed in the respective gears. It feels as if the clutch is slipping.
The problem is present in all gears, manual/auto mode, sport mode etc.
There is a more fundamental PDK calibration process that can be run via the OBD tool. This was also done but it aborted half way through. Car was immobilised because of this and then taken to OPC. They re-flashed the gear box and said everything is fine. Car is running again but the problem is still there....
Any thoughts/experience on this would be much appreciated.
My car: 997C2S from 2009
Thanks.
