Mileage when the problem started
Owner reports
Selected complaints filed with NHTSA by 2006 BMW 325i owners, lightly cleaned up (personal details are redacted by NHTSA).
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.
Air bag seat sensor failure. I would like to add my entry to the long list of BMW 325 owners that should have been covered by the front seat occupant protection mat defect recall (see NHTSA campaign number: 13V564000), but apparently are not. According to BMW, my car was made a month before I.e. Nov 2005, the recall date parameters, which stared in dec 2005. This involves a faulty passenger occupancy sensor malfunction that disables the airbags in 2006 e90 BMW 3 series sedan. BMW recalled previous years sensors but has not fixed the issue in later models. There are plenty of folks affected by this: see http://www.carcomplaints.com/BMW/325/2006/accessories-interior/seats.shtml ntsb, please address this asap! And thanks!
BMW 2006 325i taken to mechanic due to passenger occupancy seat mat sensor failure associated with recall of same model year BMW. Airbag light illuminated on dash and airbag off light sensor illuminated even when passenger seat was occupied. Manufacturer was notified, but said the VIN did not fall within the range of the recall. Did not authorize repair on the vehicle due to $700 estimated repair cost. Clearly this is an issue with the BMW 2006 325i as apparent with the number of complaints associated with this issue.
Tl* the contact owns a 2006 BMW 325i. The contact stated that the passenger seat recognized a passenger even when nothing or no one was in the seat. The dealer repaired the vehicle per NHTSA campaign number: 13V564000 (air bags); however, the failure recurred. The vehicle was returned to the dealer it was diagnosed that the leather seats needed to be reconditioned. The manufacturer was notified of the failure. The failure mileage was approximately 114,000.

The air bag light came on and I called BMW customer relations. They told me to take it to a BMW dealer to have the front seat occupant protection mat replaced under an extended warranty (NHTSA campaign number 13V564000). The BMW dealer in scottsdale said it isn't listed as a recall item and they want $180 just to perform a check to see if there is a problem, which is ridiculous there should be no fee at all to fix such an important safety item (airbag).
Airbag light illuminated on the dashboard. Manufacturer was informed but noted that the VIN doesnt fall within the range of the recall. Manufacturer didnt authorize the repair ($700 estimate). Recall 13v-564 is specifically for BMW/325i/2006/sport seat/airbag my exact car and exactly the issue im experiencing. There are hundreds of BMW/325i/2006/airbag complaints. BMW customer relations refuse to help
A faulty passenger occupancy airbag sensor warning light has been repeatedly appearing. Own research suggests that as a result of this fault the passenger airbag May not deploy in a crash. This problem seems to be extremely common to bmws from around this time and a non-deploying airbag would pose a life-threatening safety risk. BMW has as yet apparently refused to issue a recall.
My BMW does not fall into the recall that BMW published. After several lights appeared in my dash (airbag, brake, seatbelt) I had the disnostic tool looked up and received a fault code 93c3 seat occupancy detector, passenger . Looking on the web this seems to be a common problem.
