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.

You might consider taking the vehicle back to the OPC to sort it out.
Personally, with this sort of electronic wizadry, my first approach would always be a main dealer as the software upgrades and patches and equipment is often not available to indys for some considerable time. This was the case with the \Mercedes box in my daily driver - erratic shifts between 1st/2nd. An indy quoted me a figure that I discovered was the cost of them taking it to the main dealer and their costs on top for time! I took it to the main dealer and the price was less and they had all the software patches and upgrades and in 30 minutes it was done and fantastic smooth shifts.
I'm not saying this happens with indys and PDK but I'd suspect that the most up-to-date fixes, software and patches (and technical service bulletins on faults) will always be at the OPC before it hits availability at any indy.
