318iS Airbag light comes on and off when i have a passenger?
Hello all hope you can help, i have looked on here but cant find a problem the same.
I have a 2003 318i sport touring, when its just me in the car all is fine but when i have a passenger the airbag light sometimes comes on but will go off and come on when it feels like it.
There are 3 items that could be your culprit, Occupancy sensor $23.00 on ebay, the seat belt buckle maybe $76.00 and the most terrible on is the mat sensor,not too easy to get it out, the dearler will charge more then $300.00 to replace it or look for some treads on how to replace it if all else fail...since it is intermittent you know is a short somewhere base on what you wrote, weight onthe pass seat might bite some wire and causing a short...
I had a similar problem in that my airbag light came on for no reason. Turned out it was my Passenger Seat Occupancy Sensor. This is a mat embedded in the seat and if it goes bad, then the airbag light will come on and all airbags are disabled (potentially). I got mine fixed by substituting this sensor with a bypass unit which simulates a passenger all the time. Check out the website: Home
