Me to, i'm going to try to fix it today, i'll get back to you with results. Finally after 13 years, it went out. I've got the replacement part. I've checked archives and online info and found much about E30 OBCs. Any specific help on E28? It seems removing the instrument cluster would allow access to OBC... which then might have to be removed to slide out the old light bar to the right? Am I on the right track... is there an easier way?
