Air bag light

I have a 99 328i. The airbag light has been on for a while now. Finally had time to investigate under the front seats and I see that there is one connector under the front passenger seat that is not connected and two under the driver seat that are not connected to anything. Should there be any connecters not connected to anything? I can't seem to see where they would connect. Any suggestions anyone?

I am not very experienced in this area, but I think that of one of your seatbelt sensors isn't connected, the airbag light will come on. Sorry I cannot be of more help. Check back later. Someone else here surely knows more than me.

Edit: is this thread any help?

In other words the plug is at fault not the system and not the sensor. The quick fix that the guy did was to use a zip tie around the two wires to stop the plug from straining. Reset the air bag light and hey presto problem solved. Total cost £10. Above someone suggested just resetting the light. This is fine until next time you move the seat back and forth.

A BMW dealer will replace the sensor at a cost of £100-£150 per seat.

If your not sure take it to the dealer. This car has a seat belt tensioner and is activated by pirotechnic so their is a possiblity of it going off if plugged in to a different connector. I believe their are 3 small connectors under the front seats, one for tensioner, one for seatbelt light, and one on passenger side for seat occupancy sensor.

Wow that was useful to know. However the explaination i was given was that my alternator was slightly faulty and a low voltage error was seen in a lot of area's when codes were pulled from the computer. It's kinda annoying having the airbag light on and friends clown on me for having a BMW that is broken. What ever... screw them... LOL
