325i, Passanger Belt & Air Bag Light On
I have a 2002, BMW 325i. A couple of days ago the passanger seatbelt light & the passanger Airbag light came on.
I took it to the dealer today to get it fixed and he is quoting me 1000$ to replace the Module.... When I questioned how was he certain about the module being the problem & needs to be replaced. He said that it is not communicating.... Can any one help me understand how this thing functions, so I dont look dum when I go to the dealer to pick the car in next 3 hours.
