Five problems related to warning light on have been reported for the 2006 BMW Z4. The most recently reported issues are listed below.
Spring in steering wheel that is part of air bag causes warning light. Less than 50 k miles electrical issues. Have had 2 replace the batteries twice in 5 years. Having to replace the blower motor twice, and the console controls for air conditioner and heater. Lastly, when the engine is warm and you come to a stop light, the engine surges drastically. BMW service claims that it is normal. And.
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.
Front passenger air bag sensor warning light on - passenger air bag will not function in event of collision. Passenger air bag sensor warning code can not be reset. The car air bag system has never been activated by collision. The front passenger air bag warning light first appeared when starting the car in garage and is not associated with any collision events. It appears to be linked to similarly reported BMW models recalls involving the front passenger seat air bag sensor mat failures, which requires seat air bag sensor mat replacement. The problem is it is not clear if current air bag sensor mat recalls include and cover the BMW 2006 Z4 passenger air bag seat sensor mat replacement. The car was purchased from BMW dealer as a pre-owned certified car under full warranty. The dealer would not address repairs under the current recalls. Need your help, there are not that many Z4 on the road and the number of owner reported failures is likely to be a small number but this does not diminish the fact that the seat sensor mat in a Z4 are the same equipment being recalled for other BMW models. Please extend the front passenger seat air bag sensor mat recall to include the 2006 Z4 models. Thank you, bruce cromer.
