Ok I have an r53. So I know there is the whole thing with the srs light turning on randomly due to a seat wiring thing... this i think is a little different. Whenever I to start my car without my seat belt engaged the srs light turns on, but not the seat belt light. Then if i plug in my seat belt the srs light goes away, and if i start the car with my seat belt engaged to begin with the srs light never comes on. This just started a few weeks ago. Any ideas as to what is causing this?
