TAYCAN 4s blacked out PCM

[tommiwillmi]

It started with the displays—specifically the large display, the climate control display, and the passenger display—occasionally going black. The dashboard would then show ‘data is loading,’ and after a short time, it would come back on its own. Now, the screens remain black, and even the two-finger reset no longer works. I usually don’t fully charge the vehicle, only up to 150 to 200 km. It’s also kept in my underground garage, so it could possibly be due to a software update. I also had the feeling it was related to Apple CarPlay, as this issue always seemed to occur when I was logged in. Has anyone else had the same problem? I went to Porsche, and they told me I might need to replace the control unit, which is supposed to be very expensive. It would be great if there’s another way to fix this. Thank you in advance and best regards.

I had a similar issue- they just called me up and said I had a bad usb hub... I'll let you know if that fixes my issue

Same here, the dealer replaced my PCM but didn't disclose what caused this issue.
