Purpose and function in the vehicle

The presented component belongs to the Parking sensors category and is designed for installation in the front or rear bumper of selected Mercedes W164, W204, and R171 class models. As an ultrasonic sensor, it works with the factory PDC module, generating warning signals when maneuvering in tight parking spaces, approaching walls, bollards, or other vehicles.

The placement on the vehicle covers both the front and rear of the body, allowing for flexible use of the component when replacing a single sensor in a specific bumper area. This allows for restoring full functionality of the parking system without the need to interfere with other system components.

Visual parameters and color matching

The sensor is finished in Obsidian Black, which allows for a consistent match to the factory Mercedes body paint in this color. Such a solution reduces the need for additional painting and allows for maintaining a uniform appearance of the bumper after replacing the component.

Color matching is important not only for aesthetic reasons but also for practical ones – a properly selected sensor does not stand out from the bumper surface, making the installation discreet while the vehicle retains its original visual character.

Technical characteristics and integration with the PDC system

The ultrasonic parking sensor generates and receives acoustic waves, based on which the PDC system calculates the distance to obstacles. A properly functioning component ensures:

• stable object detection within the typical operating range of the parking system,
• smooth information transmission to the PDC controller,
• correct acoustic and visual signaling on the instrument cluster or multimedia screen.

As a part designed for a specific brand, the sensor is structurally adapted to the geometry of the bumper and mounting sockets in Mercedes W164, W204, and R171 models, which facilitates the replacement of a damaged component without modifying the installation.

Condition, application, and selection by numbers

The offered sensor is a used component, which in practice means the possibility of an economical repair of the parking system while maintaining the manufacturer’s original specifications. In the case of body electronics, it is essential to match by part number and interchangeable numbers – this information can be found in the technical specification section and allows for verifying compatibility with a specific vehicle unit.

To better understand the principles of selecting used modules and sensors, including the importance of OEM numbers, reference numbers, and hardware/software compatibility, it is worth reading the guide: Used automotive electronics – ECU modules and second-hand sensors. The article explains how to safely choose electronic components and what to pay attention to during installation.

Support for parking system expansion

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

Selecting the right components from one product group allows for maintaining the consistency of the entire parking assistance system, reducing the risk of system errors, and maintaining the comfort of vehicle operation at the expected level.
