宝马倒车雷达探头 66202184264 电眼传感器停车辅助精准

When your BMW shows continuous beeping when reversing, false obstacle alerts, or no response at all, after cleaning to rule out obstruction, the original rear parking radar sensor has aged or failed. When functioning properly, it uses ultrasonic detection to measure distance to rear obstacles and provides real-time feedback to the parking assist system to help park safely. This product OEM number 66202184264 fits BMW 3 Series (E90/E92), 5 Series (E60), X3 (E83), X5 (E70), and other models. Installation ensures sensor orientation marks face upward; check harness connectors for cleanliness and dryness to avoid false alarms from poor contact.
