Catching up the news tonight and the wife walks in and says that I left my headlights on but only one of them was working. I always use the off center position so I knew something was amiss. Sure enough one headlight was on, the light switch was in the "Off" position There was a code on the dash that disappeared when I started the car and ran the systems check all checked ok with no other lights.

She's a 07 92 328i coupe 6M with 90,000 and runs as well or better than day one. I've had a few of the normal maintenance items but nothing more than that. No electrical issues and battery was replaced by the dealer about 3 years and 30,000 miles ago.

Any thoughts/info appreciated.

Thanks

I was at Starbucks one time and there was an lci e92 in the lot with only one headlight on as well so you're not the only one... all I can say is hope it doesn't happen again. Canbus can trip out sometimes

Maybe weak battery?
When I had weak battery, my dome light would stay on when I lock the door.
And 2 weeks later my car would not start.
Replaced battery and everything returned normal.
