Parking Sensor Purpose and Function

The presented sensor is a component of the PDC system mounted in the front bumper, responsible for precise obstacle detection during maneuvering. Operation in the front of the vehicle requires stable performance in varying road conditions, which is why the sensor's construction is prepared for continuous cooperation with the vehicle's factory electronics.

Its placement on the front of the vehicle allows for:

• precise monitoring of distances to obstacles when parking at the front,
• cooperation with the factory acoustic or graphic PDC system,
• increased safety during maneuvers in confined spaces.

Calcite White Color - Body Matching

The sensor is finished in Calcite White - 650, enabling a visually cohesive integration with the painted bumper elements. This ensures that after installation, the part does not stand out from the bodywork, and the parking system remains discreet and consistent with the factory styling of Mercedes cars in this shade.

This color matching reduces the need for additional painting and facilitates the quick replacement of a damaged sensor with a functional part of similar visual characteristics.

Technical Characteristics and Vehicle Integration

The sensor belongs to the parking sensors category and is designed to work with the factory PDC system in Mercedes vehicles. The component's design allows for installation in the designated front bumper socket, maintaining the correct working position relative to the road surface and obstacles.

The part features dedicated manufacturer markings and assigned replacement numbers, which simplifies selecting the correct sensor based on service documentation or parts catalogs. This allows for precise verification of compatibility with a specific vehicle configuration, minimizing the risk of selecting the wrong component.

Condition, Application, and Benefits of Installation

The parking sensor is offered as a used part, allowing for economical repair of the PDC system while maintaining the original manufacturer's specifications. Replacing a damaged sensor with a functional component of this type restores the correct operation of the parking assistant without the need for intervention in other system components.

The main benefits of using this sensor include:

• maintaining the factory logic of the PDC system's operation in the Mercedes vehicle,
• aesthetic matching with white body paint in the Calcite White shade,
• the possibility of replacing a single component without modifying the wiring harness or control unit.

Selection and Additional Technical Information

When selecting a parking sensor for a specific vehicle, it is advisable to verify compatibility by OEM number and replacement numbers, as well as check the placement on the vehicle (front) and the finish color. This approach minimizes the risk of incorrect installation and ensures proper cooperation with the existing electrical system.
