Exclamation E46 Airbag light on! HELP

My airbag light has been appearing on and off. Went away for two weeks but Appeared today for a solid 10 minutes before turning off and has again come on while driving. Only happens when a passenger sits in the car. ONLY MOD EVER DONE TO CAR, WAS I INSTALLED AUX INPUT CABLE. I HAD TO REMOVE THE ELECTRIC WINDOW CONNECTIONS TO GET CABLE THROUGH. Light did ONLY come on next day after the mod. I cannot afford hundreds of dollars to repair the error.
Any HELP PLEASE? Do I need to get it fixed?

Atleast mine reacts that way, if passenger keeps knees up. But ofcourse yours might have some real problem.

Yes, lots of people have this same problem. That's because the sensor mat in the passenger seat sucks, and it's an over-engineered feature really (that's what everyone say).

So, here's the solution. I did bought the same one last week. Plugged it in, and the lights are gone.

If you want more info, just google bmw seat occupancy light

You need to get the code read to know for sure. But the two most common culprits are the seat occupancy sensor and the seatbelt buckle.

Will this bypass remove the light or will I need to reset it using the tool. Will this also fix the problem?
