Getting the 1 brake light failure message on my 97 328IS. The right brake light is indeed not working. I checked the bulb and it was fine. I replaced it anyhow with a Sylvania with no luck. I tried cleaning the connectors, same problem. I tried putting the working reverse bulb in, negative. Any suggestions? From what i've researched, the brake light switch is a fairly common problem but I'm not recieving the brake light circuit error.
thanks

Socket or wiring is bad if the known good bulb didn't work. Start at the socket with a voltmeter and start following the circuit backwards - sooner or later you'll find where the smoke got out.
I recently had the same problem with a 97 328ic. Discovered that there had been some arcing that had burned a small hole in one of the tail light housing contacts so that even with a new bulb holder, full contact wasn't being made. So i dropped in a bit of conductive solder to fill the hole and problem gone. Saved the cost of a new tail light housing unit.
This is a VERY common problem on BMW - especially whit the "galvanized" or zinc coated steel contact strips. BMW replaced the tail lamps on E38 series (7) until they were redesigned. Don't know about the other cars but I have repaired mine by scraping away the burnt area and using a decent soldering iron 30W + solder a small piece of brass over the hole or scrape off the coating and put a dollop of solder in the hole and carefully spread it out smooth. Almost a permanent job.
