Since the colder weather started when my 328xi is cold when I start it the Airbag warning and seatbelt warning lights come on (seatbelt is on), the interior lights won't work and the sunroof won't work. After 2 to 4 miles the warning lights go off and everything works. Does anyone else have this problem. I am scheduled to bring it in to my dealer, but I am curious.

battery?

battery?

I don't think so. It starts O.K. headlights work etc.

I've had it happen twice so far on my 335 sedan. It can be fixed by removing the fuse for the dome light and reinserting it (#40 in the layout). Don't ask how I figured that out.

I think it is either a sensor/electronic bug or the fuse is not engaging.

There has not been a pattern with my two occurrences, just happened seemingly at random.

Hope that helps fix the problem at least.

Thanks to all who commented. It is fixed. The problem was with the roof switch cluster.
