PCM Vertical Color Lines on Screen

[markrm61]

Has anyone experienced this error? My 2021 Taycan PCM screen showed colored vertical lines today upon power on. After a 15 minute drive and a few on/offs they disappeared and the screen normalized. I’ve had no PCM errors previously and nothing but good reliability overall with the car. Thoughts?

Need a good reset, close the car wait 45 min or unplug PCM fuse, it will get back to normal for a while...

Just a random guess: It may be a sign of bad memory/overheating, as this is kindof what I used to see "back in the days" before ECC memory was used in GPUs, as I'm an oldschool overclocker But it always looked like this if the memory was not ECC and was pushed too far.

Thanks - it seems alright now and I'll give it a reboot just in case...
