Mercedes-Benz Reverse Radar Sensor A0009051202 Parking Sensor Original Part Number Replacement

When your Mercedes rear parking radar triggers false alarms, fails to alarm, or the alarm distance shortens or the radar system has no response, this usually indicates aging or failure of the original car rear parking radar sensors (parking sonar). These sensors work by using ultrasound to detect obstacles behind the vehicle and provide real-time distance information to aid safe parking. Replacements use OEM part A0009051202; suitable for many Mercedes models (e.g., C-Class, E-Class, S-Class). Please confirm the original sensor part number is the same. Installation notes: disconnect the car battery before removal, carefully pry off bumper trim, avoid damaging harness; after installation, perform system self-check or use a diagnostic tool to match, ensuring radar function is normal.
