SRS Dashboard Light
 

The SRS light in my 2000 MB E320 SW is frequently coming on and going off.
What's the problem and what do I need to do? Thank you.

If I had to guess, I would guess passenger seat switch. But it would be a better idea to hook the car to a scanner.

I had this problem and after I changed the OVP Relay, Fuses, and Voltage Regulator in the Alternator, haven't seen it happen since. I have a 1991 300E. Others say it is the contacts behind the steering wheel and that spraying contact cleaner from the backside of the wheel could help it. A nice piece of black electrical tape works too!
