Application and vehicle function

The front PDC parking sensor is responsible for accurate distance measurement from obstacles in the front bumper area. It works with the factory control unit and the acoustic or visual system, transmitting a signal when approaching an object. In Mercedes W169, W204, and W212 series vehicles, it is an essential element of the parking assistance system, affecting the safety of maneuvers in tight spaces, garages, or during city driving.

Its placement on the front of the vehicle allows for effective monitoring of the area directly in front of the bumper, where visibility from the cabin is limited. A properly functioning sensor minimizes the risk of minor collisions and damage to body components.

Compatibility and integration with the PDC system

The offered item is designed for the factory parking system in selected Mercedes models, which facilitates its integration with the vehicle's existing installation. Due to compliance with the original manufacturer's specifications, the following are maintained:

• correct communication with the PDC control module,
• appropriate distance measurement characteristics,
• consistent operation with other sensors in the vehicle.

Such a fit promotes stable operation of the entire parking assistance system, without the need for modifying wiring harnesses or software.

Tenorite Grey Metallic – 755 finish

The sensor is finished in Tenorite Grey Metallic – 755, used in the Mercedes paint palette. Proper color matching to the bumper is not only aesthetically important but also practical – the element does not visually stand out from the body, which is particularly important in premium class vehicles. A uniform finish also limits the risk of unwanted light reflections in the measurement zone.

Characteristics of the used component

The presented parking sensor is a used component, which allows for an economical repair of the PDC system while maintaining original specifications. Such components are often chosen for servicing older vehicles, where a reasonable balance between cost and maintaining factory functionality is important. A used sensor, after proper installation and potential calibration, can effectively restore the correct operation of the parking assistance system.

Practical installation and operational tips

When replacing the parking sensor, it is worth paying attention to:

• the condition of the socket and electrical wiring in the bumper,
• the cleanliness of the sensor's working surface after installation,
• proper seating in the bracket, without play or tension.

After installation, it is recommended to perform a PDC system test using a factory diagnostic interface or a suitable tester to confirm correct communication with the control module and uniform operation of all sensors.
