About part number A2125420018

A parking sensor is an electronic driver assistance component fitted to the front or rear bumper. It connects to the vehicle's wiring loom and parking control module, using ultrasonic waves to measure the distance to nearby obstacles. When the system is working, it provides the driver with audible satisfy-beeps or visual displays that change in speed or colour as the vehicle gets closer to an object, helping to prevent low-speed bumps while manoeuvring into tight spaces.

To confirm that this Mercedes part is the correct one for your vehicle, you must check that the manufacturer part number A2125420018 matches the number printed on your existing unit. This part number is usually stamped or printed directly onto the plastic housing or near the electrical connector plug on the back of the sensor. Matching this number exactly is what determines if the part will fit and function properly.

When replacing a parking sensor, you often need a replacement rubber sealing ring or silicone washer to keep moisture out of the bumper housing. Parking sensors are usually replaced because they have suffered water ingress, stone chip damage, or an impact to the bumper, which causes the parking assistance system to display a fault light or produce a continuous warning tone.
