Dave Tostenson Subject: Firmware Upgrades?

1 Answer

I have had various electronic glitches with my 92′ 735i that have all the signs of firmware bugs. For example, last night I get a “1 Brake Light” message, but the brake lights are fine, and after the message clears my trip meter goes to zero (000.0). For that matter, my trip meter has gone to zero several times of late for no apparent reason. I have also had the problem where the engine is hard to start and I get the “Check Control” message. I suppose it is possible that I have a hardware problem that is causing these odd behaviors, but it feels more like code problems to me. Has anyone heard of BMW providing firmware upgrades to the computer system on the car?
