If you have other reasons to get back there, certainly check it while you're in there and maybe proactively give it a quick wrap in electrical tape while you're there for some extra coverage.

I'm guessing that this is a pretty odd occurrence with these cars though, and isn't really reason for everyone to quickly tear into the wheel well.

I just thought I'd post it if someone was trying to track down a strange electrical gremlin, as a place to check for an issue.

My 528iT wasted enough of my time in that realm, if the info helps one person, it was worth typing it out.

Looks like the car isn't being picked up until tomorrow, so I'll have to wait until that point to get a photo of what happened.
