How to Resolve BMW Brake Failure?
1 Answers
After emergency operation ensures power supply again, the parking brake button must be pressed 3 times. The control unit intends to release the brake. However, the brake has already been released via the emergency unlocking device, and the motor will not rotate backward. The motor can rotate forward, the brake engages, and the control unit recognizes this situation. The motor can rotate backward, the brake is released again, and the operating mode is re-established.
