How to deal with the abnormal noise of BMW X3's auto hold?

BMW X3's auto hold abnormal noise is the sound of brake pads. Introduction to auto hold: Auto hold, also known as AUTO-HOLD, refers to an automatic braking function. After activating this function, for example, when stopping at a traffic light, it is equivalent to not using the handbrake, which can simplify the operation by avoiding the use of the handbrake or electronic handbrake. For automatic transmission models, there is no need to frequently switch between D to N or D to P. Working principle of auto hold: The AUTO-HOLD auto hold function provides accurate parking force through the slope sensor by the controller. During startup, the parking control unit calculates information provided by the clutch distance sensor, clutch engagement speed sensor, throttle pedal sensor, etc. When the driving force is greater than the driving resistance, the parking brake is automatically released, allowing the car to start smoothly.
When it comes to the automatic parking noise in my BMW X3, I get really anxious! I've encountered a similar situation before where the brakes made a creaking sound when parking. It's mostly due to dust accumulation or rust on the brake discs, especially after rain when mud tends to stick, causing abnormal friction during parking. I tried driving a short distance to wear it off, and sometimes the noise disappeared. But if it happens frequently, it might be uneven wear on the brake pads or debris stuck in them. I usually maintain the brake system regularly, and rinsing the wheels during car washes helps prevent dirt buildup. I suggest you get it checked as soon as possible, otherwise, it could affect braking performance over time—don’t let safety risks pile up.
