So finally I also got this message. Gladly I was fast enough to leave the autobahn but came to a stop at the side lane of the exit. Turned it off and on again. Everything was working again. When the message occurred, I could not accelerate any longer, just braking without recouperation and steering.
Possible reason: I switched the internet radio stations and then the the top line of the favourites disappeared. The pcm, upper Display in the middle, freezed and stopped working. The lower display eg navi or music button „clicked“ but the pcm didn’t react. The two finger trick didn’t work either. The navigation with range manger was active before that happens.
Driving still worked without a problem.
But then I changed from sport plus to sport mode with the knob on the steering wheel. The moment I turned it the message occurred and the car stopped.
My opinion - non expert, not even too interested in computer technology- the pcm freezed like a windows Computer. With changing the mode, the „driving computer“ tried to communicate with the pcm, maybe for telling the navigation that an other drive mode was acitivated. The pcm didn’t answer, so the car went totally on error.
My suggestion: if the pcm freezes or stops working during driving, don’t change the mode. Just drive to the next parking and turn the car off an on.
I informed the dealer. They checked the car and forwarded the problem to porsche. But there is no solution yet.
Car: 4s 2021 after the big update.
