宝马泊车传感器 66206989067，电眼检测器探头倒车雷达，安全驻车

BMW parking sensor 66206989067 (original 6989067) installed in front and rear bumper mounting holes, uses ultrasonic transmit/receive to monitor obstacle distance in real time, core component of the parking radar system. When obstacles are detected, beeping frequency changes to warn the driver and assist safe parking. Installation difficulty low; recommended work time 30-45 minutes; remove bumper cover and carefully handle clips. If the system beeps continuously, has no response, or reports intermittent false alarms, the sensor may be faulty.
