My wife's airbag light is on. It came on when she ran into the receiver hitch of an suv and stuck it through the front bumper cover. She took it to the vw dealer today---they told her it was her seat belt not sending a signal to the airbag and would cost $433 to repair. She brought it home cause we were a little financially challenged after the $260 MAS they installed to correct the loss of power and the $90 fee to tell her it was the seatbelt causing the airbag light to come on. I'll check for loose or broken wires tomorrow---any other thoughts would be greatly appreciated. What is a vagcom?2001 tdi new beetle
