The vehicle was taken to the dealer and no cause for the failure was determined. The vehicle was not repaired. The manufacturer was not notified of the failure.

The contact owns a 2006 BMW 325i. The contact stated that while operating the vehicle, the front passenger's side air bag warning light would remain illuminated. The vehicle was taken to the local dealer who diagnosed that the seat mat sensor was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was not yet notified of the failure. The failure mileage was 180,000.
Put a box of moderate weight into the passenger seat (hard drives) - probably 40 lbs. After driving for a few minutes and over a few bumps, the seat belt warning light came on because the seat sensor was tripped by the weight. Put the seat belt on to silence the warning. Shortly thereafter, both the seatbelt and passenger airbag warning lights showed on the dash, regardless of occupancy. Hooked up to scanning tool and cleared the codes but they always return. This is not a rare event from reading the online forums - it is likely due to the sensor mat in the seat for occupancy being defective, or a combination of that and the seat belt pre-tensioner being defective, for the passenger side only. The vehicle operates normally other than the warning lights. Obviously have not tested the airbag, but that is highly unlikely to be the actual problem from my investigation of the symptoms.
The passenger seat occupancy sensor (OC3 mat) on my 2006 BMW 3 Series (VIN: [redacted] ) has failed. As a result, the front passenger airbag is disabled, which poses a serious safety risk. BMW issued a 15-year warranty extension for this issue, acknowledging it as a common failure, but my vehicle is now slightly outside the coverage period. This part is vital for detecting front-seat occupants and enabling the airbag during a crash. I believe BMW should still be required to fix this safety-critical defect, especially in vehicles where the issue was never repaired while under the extended coverage window. This should be reclassified as a full safety recall, not just an expired service campaign.
Existing vehicle recall excludes this particular VIN among the same MY and model even though this VIN is affected. Report Receipt Date: NOV 12, 2013 NHTSA Campaign Number: 13V564000 Component(s): AIR BAGS Potential Number of Units Affected: 76,565 Manufacturer: BMW of North America, LLC SUMMARY: BMW of North America LLC (BMW) is recalling certain model year 2006 325i, 325xi, 330i, 330xi sedans and 325xi sports wagons, [shortened]. The front passenger seat occupant detection mat that determines if and how the passenger frontal air bag should deploy in a crash may fatigue and develop cracks which could lead to a system failure. CONSEQUENCE: Should the system fail, in the event of a crash, the front passenger air bag would be deactivated, increasing the risk of personal injury.
The passenger seat mat sensor stopped working and that disabled the airbag. I called BMW and they told me this part has already been replaced once in 2016 on my car during a recall, which happened before I purchased the car. I asked them to replace it again since this is a safety issue and they told me BMW would only replace this part for cars with less than 15 years, which in my case expired on January 2021. This is a very costly repair and in my view is caused by a poorly designed part, considering that there has already been 3 recalls on it and it keeps breaking after a some use. So for now, until this case is settled, I will be driving a car with the passenger airbag deactivated by the board computer, what is a very serious safety issue.
Component failed: passenger seat occupancy sensor (BMW error code: 0x93C3) Implication: passenger airbag will not deploy in case of accident if the occupancy sensor is defective. Similar problems: similar recalls were issued by BMW for the same model and year but with only sports seat; regular seats were not recalled. Previous inspections: this issue has not been previously inspected, but personal inspection leads to faulty seat occupancy sensor. Prior warnings: dashboard shows seatbelt and airbag lights; roof indicator lamp shows passenger airbag off.
There is a recall 17v-428 for the seat mat, and i went to my local BMW dealer and said this car was not on the list, but they acknowledge it's the same issue but because this VIN was not included they can't fix it at no charge . They want $2100 to repair. Can you help me ? Thanks
