Purpose and function in the vehicle

The presented sensor is a component of the PDC system responsible for monitoring the space in front of the vehicle. Mounted in the front bumper, it works with the factory electronics, generating warning signals when approaching obstacles. As a result, the driver receives clear information about the distance to objects, which reduces the risk of damage to the bumper, headlights, or structural elements.

Its placement in the front part of the car allows for effective support when parallel parking, pulling up to a wall, post, or another vehicle. The sensor operates based on the manufacturer’s factory parameters, which promotes stable, repeatable detection characteristics.

Color and visual fit

The element is finished in the Cavansite Blue Metallic – 890 shade, which allows for aesthetic integration into a bumper painted in the same color. Thanks to this, the sensor does not disrupt the body lines and does not require additional painting, provided the vehicle has a matching paint code.

Choosing the right sensor color is important not only visually but also practically – it limits the need for additional paint work and shortens the time required to restore the vehicle to full efficiency after bumper repairs or replacing a damaged PDC system element.

Technical characteristics and integration with the PDC system

As an original part for the Mercedes brand, the sensor is designed to work with the factory parking system in selected models of the W169, W245, W204, and W212 series. The design, adapted for the front mounting zone, allows for proper seating in the bumper socket and correct orientation of the measurement beam.

In practice, this means:

• reliable integration with the factory electrical harness and PDC control module,
• maintenance of the sensitivity and detection range intended by the manufacturer,
• stable operation under typical operating conditions (city maneuvers, parking in garages, narrow parking spaces).

Selecting the sensor according to the manufacturer’s markings and compatibility with the specific vehicle generation minimizes the risk of system errors, incorrect readings, or fault messages on the instrument cluster.

Component condition and mounting aspects

The offered sensor comes from the category of used components, which allows for an economical repair of the parking system while maintaining the original specification. This type of solution is particularly beneficial for comprehensive bumper repairs when it is necessary to replace several sensors at once.

During installation, it is worth paying attention to:

• proper seating in the bumper socket,
• cleanliness of the sensor’s working surface (no thick layer of dirt or paint),
• secure connection to the electrical harness, without looseness or damage to the connectors.

A correctly installed sensor allows for the restoration of full PDC system functionality without the need for vehicle software intervention, provided the replacement takes place within the same component generation.

Selection support and system expansion

If you are planning a comprehensive repair or upgrade of the bumper area in your Mercedes and need other elements from the same group, such as additional sensors, mounting elements, or compatible control modules, check the available parts in the Mercedes parking sensors category.

When choosing a used PDC sensor, it is crucial to match it to the vehicle’s electronics and the correct manufacturer markings.
