I have a 1994 730i e38 and it is great except for the brake lights are stuck on. No warning messages, the dignostic system can't detect it and they haven't a clue at my local BMW dealers. They wanted £75 per hour + VAT + parts to have the apprentice check all systems ( the diagnostic already says no problem present!) and he knew less than me. Their idea I think is to keep replacing parts until it's fixed and I can do that at £0 per hour plus parts. It's not the switch, I have checked and all connections are fine and uncorroded. Light control unit? Don't want to buy one at £250 and find it's not. Anyone have any clues?
Thanks, It's a great car but this is driving me nuts.
