I have a problem with the passenger seat occupancy sensor. It doesn't understand if someone is seating and the seat belt warning light doesn't turn on if the passenger is not wearing his seat belt. Assuming that the passenger wears his seat belt, in case of a collision will the airbag deploy? My car is a VW Jetta 2008. The manual doesn't describe this case so I want to know if I should replace this part or it doesn't worth the money.
EDIT: I went to my mechanic and he said that in order the airbag to be deployed it needs only to sense that the passenger is buckled up. Is there any vw standard to reference?
