Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering airbags on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
A check control message (CCM) for the restraint system (Air bag) appears. In the instrument cluster, the red air bag warning light lights up permanently. One of the following fault codes is stored in the ACSM (air bag control unit): 930949 - Knee airbag, driver: short circuit to negative terminal 93094F - Knee airbag, front passenger: short circuit to negative terminal 93094C - Knee airbag driver's side: Resistance too great 930952 - Knee airbag, front passenger: Resistance too great

What owners are reporting 1 most recent
The driver passenger restraint system light comes on which is a manufacturer defect that should be covered for the life of the vehicle (this is not a wear-and-tear) component. I called BMW and was told that the part is out of warranty. I would like an investigation of this part for all BMW X3 as the defect can result in fatalities.
