We would like to turn off the passenger airbag at our mini, at BMW it costs about 400€ since it allegedly has to enter a new belt. Can one explain this to me? What is the difference? Background is that we would like to take our baby to the passenger seat? Or can you just regulate it so that the seat is pushed to the rear? P.s. That the airbag lamp would be on then is clear… Mfg Tom
