The little light-up sign on my ceiling that say the airbag is not on (when the passenger seat is empty) in my 745i sometimes is on and sometimes is off. The other night it went on and off several times while I was driving home. Is this likely a problem with the actual airbag or do you think the stupid little light is not working? Anybody else have this problem? My dealer is a couple hours away and I am not due for oil change for a couple of months so it is a real hassle to take it in right now for a stupid little light. Thanks.
