My wife just got a 2009 2.9 Cayman PDK. The dealer in Livermore says there are no servicing of the PDK required. I don't buy that and I am sure that a fluid change could be helpful in smoothing things a bit. Has anyone gotten theirs serviced and what exactly was required. I read there are actually two oils used to change the gearbox and clutch pack. I appreciate any feedback from those who may have had this done and what to expect. Car has almost 70k on it and all services have been done but none on the pdk.
