Oh man, I hope you have a better result than I did with my 09 2S. Mine failed when I tried to pull away from a traffic light a year ago. Got the transmission emergency run on the dash. Car wouldn't move forward or backward. The gear indicator flashed back and forth between 1 and 2 when I had it in drive but the car wouldn't move. Couldn't clear it with Durametric while at the traffic light. Shift rod 3 failure. Towed the next day to a PIWIS which cleared some of the codes but could not clear the Shift rod 3 error. Tech tried first to run PIWIS calibration routine and then to reflash it - both to no avail. I was out of warranty and ended up paying for PCNA re-manufactured unit to be installed. Based on other failures he had seen, tech thought the issue was in the hydraulic section of the box but of course Porsche doesn't share what they found when the failed unit was opened up in Germany. What part of the country are you from?
