What I'm getting from this discussion is that some of us consider this a normal function and some not .
I would like to think of this as a feature where the system is testing brake function and therfore when I press the brake and the light goes out I could be reassured that everything is working fine. But the check system isn't really checking the brake system, is it? My impression from the schemantics for the brake light check system is that it only checks whether the bulbs are ok.
From what I have read it could one of the following:
1. normal operation.
2. brake switch - if it is indeed a 2 step switch.
3. wrong bulbs - may have something to do with resitance sensitivity.
4. check relays - two of them one in the rear and the other in the high mount brake light.
5. check panel itself.
P.S. I apologize for using the word 'annoying' as it is really not considering the fact that I truly love these cars.
: I have had the same "check light" feature on my '85 535i that is described. The unusual thing is that I didn't work that way when I purchased the car about two year ago, then it was functioning normally. Currently, the check brake light bulb remains off when I start the car, but works if I remove a brake light bulb. Strange but true.
