    Air bag light

    Dealer says the dash light may be due to either seat belt latch gone bad or the occupancy sensor mat in seat. Does a '99 E36 M3 even have a sensor mat? We're talking approx $500 vs $2000 here!!!

    Yes, they do have seat sensor mats.

    To avoid the cost and overcome the airbag light always coming on, you could build a resistor pack to always keep the passenger airbag on.

    Check and reseat all of your connections to the seat first. Then reset the light and see if it comes back. I had the same problem on my '99 M3 and that fixed it. It never came during the three years I owned it. If you need to go the sensor mat route, I have seen write ups on how to do it yourself. It looked tedious but doable. Fortunately I did not have to go that route.

    Good luck

    Mine will come on when I have a passenger in the car. When they get out I just punch the seat (with the car running) until it goes out - usually work pretty quickly

    I believe there was a MAJOR recall just a few years ago on the seat occapancy sensors for just this reason. Its worth a call in to the dealer to find out if you'll be covered.

    I believe one of the problems with the passenger mat was that the wire was too short.

    Air bag light

    I was able to abolish the light with the Peake reset tool. And it stayed off for an extended time. So I didn't worry about it. If you would like to borrow the tool, contact me for a loaner.
