Default PCM blanked out

My PCM blanked out today. First time ever after over 10k miles driving.

Anyone had this happen?

Is this a sign that it’s time to trade in my car?

Im not going to deal with delays, fixes, etc. I’ll just get rid of the car if this is going to be a headache for me

Hold the phone brother!

Don't junk the car or sell it, it's tech and can happen from time to time. If it continually happens it may need an update

Yeah after locking the car and coming back a little while later it was back to normal.

I got ahead of myself there, I think I was influenced by the thread from the guy who’s instrument cluster went black and it ended up being a huge headache for him.

The only way to reboot is to lock the car, wait a while, and come back, correct?

In my case it rebooted by itself and came back up.

S*** happens. It’s a computer. Wouldn’t think twice about it.

I suspect it like most of the intermittent PCM errors, just turn the ignition off and then immediately back on. I've even done it at a stop sign.

^ I tried that at first with the car locked for a few minutes and it didn’t work.

I think the car needs to be locked for a bit longer. Maybe 10 minutes? Perhaps it doesn’t go into full “reboot” mode until then?

Mine rebooted for the first time yesterday. As I was driving, using apple CarPlay, the screen went black for several seconds and then came back on and continued playing CarPlay. After about 5 minutes, it blacked out again. This second time, CarPlay was no longer an option on the menu. When I got home, I parked, unlocked, and came back a couple hours later and it worked fine
I hope this doesn’t become a regular occurrence

I've had it happen once and came back a couple hours later and the issue never returned.

Happened twice when it was having difficulties syncing/connecting to my Carplay. Shut off the car, locked it and came back 10 mins later all normal.

I take it as a "VW bug".

I see a common theme of Carplay with this issue.

I wonder if I accidently somehow activated Carplay and that's why this happened.

I stopped using Carplay with this car about a year ago...

I use Android. But just now my car screen did this. and then rebooted to a bunch of messages about Car Play.
Maybe there is an OTA update getting pushed?

Just to add this for the record, mine did this today at about 28k miles for the first time. PCA screen went black, was playing SiriusXM which stopped, had CarPlay active but not connected yet. After about 3-4 minutes the PCM started back up (rebooted), all by it self. So far, hasn't happened again.
