NHTSA Complaint #11441776 — 2006 BMW 330XI

We took our recently purchased BMW 2006 330xi in for recalls and a few fixes. However, the BMW service center wasn't able to fix one of the issues through the recall process since it doesn't show up for our vehicle. However, everything that I read suggests that it was a recall for this make and model. We are not sure if it was supposedly addressed before we purchased the vehicle and it is now a reoccurring issue or it is a first-time issue. The airbag/seatbelt warning light is present for passenger seat occupancy detector faults. The BMW service center said it was the sensor in the front passenger seat and offered to fix it for $1000 plus. We opted to not fix it until we checked further into the situation. The light for the passenger airbag saying that it is off is currently lit, and the airbag/seatbelt light remains on at this time. Looking for more information on this issue.
