Default pdk programming error help

this is first time i use ipwis3 software.
i have 2012 panamera 4s 4.8L (USA version if it meter?)
i made automatic update to the pdk.

Usually when you brick a module like this the dealer is the only one who can fix it for you, but I have never gone thru this. Hopefully someone else chimes in with a better solution.

Yes you need make automatic coding. For 2012 there is no update to make.
Piwis is not easy to use and it's very dangerous to use it without formation.

Yes you're right. Automatic coding should code back to what's in the build order to the car.

I also had this same problem when trying to update the tcu software with Piwis 3,so what I learned was that the MCR data error is the calibration values got wiped out during programming,so my fix was to manual program tcu only in engineering mode after that finished when straight into Pdk calibration and to
make it all the way through the fluid temp needs to be 60c and a few other pre conditions met after the calibration completes clear all error codes and mine was fixed.. I even done this on a panamera 970 with a bad tcu,got a used tcu from salvage yard and did these same steps worked like a charm even on a
used Tcu from another donor car,hope this helps someone out !

is automatic coding only possible if you created a (backup) file yourself or is it in the piwis software?
