Purpose and function in the vehicle

The presented sensor is dedicated for installation in the front part of Mercedes vehicles from the W204 and W212 series, where it is responsible for continuous measurement of the distance from obstacles. Operation in the front bumper zone allows the PDC system to generate warning signals when approaching objects, which facilitates parallel parking, pulling up to walls, bollards, or other vehicles.

The component works with the factory parking system controller, ensuring correct signal interpretation, appropriate distance scaling, and consistency with the visualization on the vehicle's display (if provided in the given configuration).

Performance parameters and color

The sensor intended for front bumper mounting is finished in Horizon Blue Metallic - 391, which allows for an aesthetic match to the vehicle's paint in this color. The use of the correct color reduces the need for additional painting and helps maintain a consistent look for the bumper.

As a body electronics component, the sensor is designed to operate in variable weather conditions, near the road surface. The appropriate housing design promotes resistance to moisture and dirt, and correct installation in the bumper socket ensures a stable position and the proper measurement angle.

Condition, fitment, and installation

The offered sensor is a used part, which in practice means it has been removed from a vehicle and verified for suitability for further use. Choosing such a solution allows for reduced repair costs while maintaining the original vehicle manufacturer's specifications.

Before installation, it is recommended to:

• check compatibility with your vehicle model based on the OEM part number and interchangeable numbers,
• verify the location on the vehicle to select the correct component for the front body zone,
• check the correct operation of the PDC system after installation (acoustic test and, if necessary, computer diagnostics).

Using an original sensor from the same model family promotes plug-and-play installation, without the need for modifications to the installation or interference with the electrical wiring.

Benefits of using an original parking sensor

By choosing this sensor model, you gain:

• consistency with the factory PDC system – correct operation of audible signals and any graphic indications,
• aesthetic match thanks to the Horizon Blue Metallic - 391 paint,
• the possibility of an economical repair of the parking system while maintaining the original design of the component.

Using a properly selected sensor translates into the comfort of daily vehicle operation, reduces the risk of minor parking collisions, and supports keeping the bodywork in good visual condition.
