Hi , I am not sure as to why the SRS light came on? Last night the car had been driven home and everything was fine. This evening the light was on and I haven't a clue. Any one have any ideas. I've had the car for a almost a year already. Thanks.

This should be in the E36 Tech forum.

Parts of the airbag system fail all the time on these cars. It could be one of the seat occupancy sensors or a seat belt sensor. The latter is easier to fix.
