: odd alarm/warning noise

03-06-2006, 11:25 AM
I have a 1998 740iL. I have had this for about 4 months now, and had never before heard the noise, nor noticed the sensor which became apparent yesterday to me.

On the steering column, right behind the steering wheel itself, there is a small sensor that looks like a 1/4 inch diameter clear plastic circle. On either side of that sensor, set into the sides of the steering column, are two small red LED like lights. Yesterday this started making chirping and beeping noises at random while i was driving, sounding much like a radar detector might. To my knowledge, unless this is some form of built in BMW detector, i have no radar detector.

This thing, and noise, is baffling me. I receive absolutely no warnings on the dash, the car drives just fine and exhibits no problems at all.

Any idea what this is? How i may disable/fix it? Anything at all is very helpful and appreciated.

perhaps some sort of airbag warning?
I don't know the car, just a guess.
