Most of these (I cannot say I read them all) seem to refer to the camera going out (I assume like black).
I had a spell Saturday where the camera just showed a color test patter, vertical color bars and no picture.
Stopped and started engine - no impact. After it was stopped for 20 minutes or so (presumably causing a reboot) it worked fine.
Anyone seen this failure mode?
Interestingly enough this happened at the BMW dealer where I was picking up parts. Naturally, despite being open for service Saturday, no one was there who knew anything about it. I scheduled an appointment then before I left (after it sat a while) it was working.
