Three problems related to front seat head restraint have been reported for the 2006 BMW M5. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2006 BMW M5 based on all problems reported for the 2006 M5.
The vehicle warning system displayed a passenger restraint fault which disables the passenger air bag deployment. The problem was initially intermittent, but within one week is now permanently displayed. A diagnostic scan by my dealer indicates a fault with the passenger seat occupancy sensor(s). This same problem resulted in a recall for other models/years, but apparently not this one for some reason. The dealer quoted $2500 for the required repair/replacement. Meanwhile, any person in the front passenger seat is not protected by the air bag.
Passenger occupancy sensor is bad. This causes a warning message to occur that states that the restraint system is malfunctioning. After further research, if this message is displayed, the airbags will not deploy in the event of a crash.
The passenger restraint system, airbag, seat belt, belt tensioner warning showed up in the car computer. Went to the dealer and dealer said that they will need to replace the passenger seat mat sensor and battery safety terminal. The cost is around $3500. When I searched online I found that the BMW 5 series 2004 - 2006 has a recall on this item already - please link. . Read more...
