What to do if the parking brake of BMW X3 fails?

[VonNadia]

The solution for the failure of the parking brake in BMW X3 is: If the power supply is restored after emergency operation, the parking brake button must be pressed three times. Relevant information about the automatic parking is as follows: 1. Introduction: Automatic parking, also known as AUTO-HOLD, refers to an automatic braking function. After activating this function, for example, when stopping at a traffic light, there is no need to pull the handbrake. It simplifies the operation by avoiding the use of the handbrake or electronic parking brake, and for automatic transmission models, it eliminates the frequent switching between D to N or D to P. 2. Working principle: The AUTO-HOLD automatic parking function provides accurate parking force through a slope sensor controlled by the system. During startup, the parking control unit calculates information provided by sensors such as the clutch distance sensor, clutch engagement speed sensor, and throttle pedal sensor. When the driving force exceeds the running resistance, the parking brake is automatically released, allowing the car to start smoothly.
