PDK Shift Mechanism Won't Change Gears

[JCyoda 1]

Went to the garage, started my car, pulled out of the garage, braked to stop to check that my garage door closed (5 sec max), applied some gas and nothing happened. When I tried to change the gear selection, the gear indicator in the tachometer didn't show at all.  Pushed it back into the driveway as best I could. I have tried it several times with no luck. No fault lights have come on!!  I looked here in the forum but didn't see any postings that were similar.  Five days previous to this event, I returned from a spirited, three state sampling (1900mi) of the twistys and mountain roads, only smiles as a result.  Anyone have any thoughts?

Do you have a durametric you can use to pull some codes? I believe the PDK will flash something in the gear indicator if it is in limp home mode but this may be more subtle than that.

Yes, I have a "FIXD" device that reads the codes, and told me that there were no error codes!!🙁 Maybe I will go check again.  Thanks for the note.

Many OBD II scanners do not successfully read Porsche codes, particularly for something like the PDK.  You need a Porsche specific tool ( Durametric, PIWIS).

Just to be clear, the shifter isn't frozen, it seems normal, but seems like the transmission doesn't get the message.

I now have it in for diagnosis at a reputable Porsche shop.

Please, do report back on findings.

Well, I have the diagonsis now and the result is grim!  After multiple attempts to reset the PDK brain, the conclusion is that i need another (new) transmission to the tune of about $25K for R&R and new transmission.    This a know problem tho' rare. Remindes one of something called " IMS"! Eh?

I am getting a second opinion, but I think I am screwed.  If I sell it as is, it's a big lose and I still need a "new" car, or if I fix it the bottom line on my investment goes up by 25K but I still have my Porsche..... I guess it is a no-brainer.  😒

Sorry to hear of your predicament.  The PDK is ultra complex internally, with even the dealer techs limited to what they can do to repair them.  These internals require very specialized fixtures and tooling, which is beyond even the dealer’s capabilities.  Good luck with your next steps.......

Thanks for that, I guess it is the price we pay to develop mind-blowing technology.
