BMW X3 airbag, ABS, and 4x4 lights on with vehicle unable to move, requiring transfer case service on BMW X3

Some BMW X3 owners report experiencing significant issues when the airbag, ABS, and 4x4 lights illuminate, indicating potential faults in the transfer case and rendering the vehicle unable to move. These warning lights suggest a malfunction in the transfer case monitoring system, which may require immediate service or repair. The ABS light indicates that the anti-lock braking system is disabled, while the BRAKE light signals a braking system malfunction, necessitating urgent attention to prevent brake failure. Additionally, the illuminated 4x4 light may point to transfer case issues, as it is responsible for power distribution between the front and rear wheels. Fault codes related to the transfer case can provide essential diagnostic insights into the underlying problems triggering these warnings. Contributing factors could include a faulty transfer case motor, corroded connections, or leaks. It is crucial for owners to have the transfer case and related components inspected by a qualified mechanic or at a BMW dealership to address these issues promptly, as ignoring them can lead to further damage and safety risks on the road.
