About 9 years (2015) after purchasing vehicle the airbag warning light began illuminating constantly. The vehicle was purchased new and had approximately 55k miles when issue began. Vehicle has never been in a minor or major accident. Vehicle was taken to an independent mechanic, but diagnosis could not be determined. Contacted bmw about issue, but was told my vehicle was not covered under any of the airbag recalls they've initiated. No action was taken by me to determine root cause and continued to utilize vehicle with air bag light always illuminated. In february 2018, received a letter from bmw regarding warranty extension to 15 years for front passenger seat occupancy mat (oc3) for air bag system. Believing airbag issue was due to oc3 mat, brought my vehicle to local bmw dealer to get repair. Bmw diagnosed the issue as a "restraint pass lower belt unit faulting" and not oc3 mat. Had repair performed successfully.

Recently purchased a 2008 bmw z4. After a week of ownership the airbag light came on. Fault code points to the passenger seat occupancy sensor oc3. Bmw issued a 15 year extended warranty to many bmw models including the 2006 and 2007 z4 with comfort seats, but not to the 2008 model. This repair costs upwards of $1500 and is safety related. Bmw needs to step up and cover all affected models!

Dashboard airbag warning light came on - obd scan indicates the passenger seat oc3 airbag sensor mat has failed. I believe this means the vehicle can no longer detect if there is a child in the passenger seat, and will deploy airbags regardless of passenger weight. Bmw has a service bulletin for many other models and years (including my z4 model - but not yet for my 2008 model year).

Takata recall. Bmw sent recall notice for airbag before expiration date. I called bmw and they gave me a expiration date to take car to dealership to have repaired. I took the car to a new sewell bmw dealership in grapevine tx, USA before the expire date given by bmw. They asked if the airbag light was displayed. I replied it was reset years before and hasn't been displayed since. Sewell said they would not look at replacing airbag without paying for diagnostic and airbag up front. I know it hasn't been replaced, but had to decline for upfront costs with unknown reimbursement. Sewell pulled up the VIN details on my car. No airbag replacement. I'm sure the replacement date has expired by a year. . . But I tried. Just got a big 'not interested' by the bmw dealership in grapevine, tx. (p.s. Was reminded by the morgan freeman takata airbag commercial on a&e tv channel airing 8/9/19)

'airbags have never been deployed according to carfax history. I was commuting home, waiting at a stop light, when I heard a very loud pop. At first, I thought something had fallen on to my car because the dash did not explode. Reveraling the airbag. I started to smell smoke coming from the passenger side and noticed that the airbag light was on. I wasn't able to start the car given the battery safety terminal disengaged. I am lucky that the driver side airbag didn't deploy, or even deploy while I was driving.
