weird behavior
 
I have something that just popped up recently on my 97 528. One Sunday morning as I was driving to the Miramar Air Show at +90 mph (hey, it was Sunday morning and no one was on the road), my emergency flashers came on, all the doors unlocked, and the dome lights came on. I first thought it had something to do with the speed, or I may have hit the emergency button (but how does that also trigger the other items?), or maybe it was just some Karma joke telling me to slow down, which I did after turning off the flashers (no need to draw any more attention to myself). When I finally parked, I noticed that the dome lights would not turn off until I unlocked, then relocked the doors. This also happened to my wife and son, and to me again a few days later. One very big downside of this is that we might not lock the doors and the lights stay on which drains the battery, and now I need a jump. I cannot relate it to anything else being turned on or off, and am told it might be related a module which might need to be replaced. Any thoughts?
Thanks Bimmerfest Forum people,
Mike

Measure the battery voltage after the car sets overnight, before and after you start the engine.

Before s/b 12.5+; after, 13.5 14.

I don't know how or why, but your car thought it had been in an accident. Those are all safety features triggered automatically when you have an accident.

Was you wife driving 90, too?
 
Just asking. Need all of the symptoms.

Ed, I'll measure those voltages and see what I get. Good thought and I know where you're going with that. Chief & BigCo, interesting you note that because my airbag light has come on and I wonder if something came disconnected in the steering wheel airbag. It was removed when I needed the ignition switch replaced and i wonder if the mechanic's work came partially undone. Mr. Magoo, no the my wife was not doing 90, and this also happens at much slower speeds. Thanks for all the input. I have some work to do.
