Purpose and function in the vehicle

The presented PDC sensor is dedicated to Mercedes W164, W204, and R171 class models, where it works with the factory parking assistant system. The component can be installed in the front or rear bumper area, making it suitable both as a replacement for a damaged sensor and as a supplement for a missing element in an existing installation.

A properly functioning parking sensor ensures:

• accurate obstacle detection in the immediate vicinity of the vehicle,
• correct operation of the PDC system's acoustic and visual signals,
• more predictable maneuvering in city traffic and during parallel parking.

Color and visual matching

The sensor is finished in Obsidian Black Metallic - 197, which allows for aesthetic integration into bumpers painted in the same shade. As a result, the component does not disrupt the body lines and maintains visual consistency with other bodywork components.

Selecting a sensor in the correct color reduces the need for additional painting and speeds up the installation process, which is particularly important for quick post-accident repairs or fleet service.

Technical characteristics and integration with the PDC system

As a component originally intended for Mercedes systems, the sensor is designed to work with the factory wiring harness and the parking system controller. The appropriate housing geometry and connector facilitate installation in the bumper socket and connection to the electrical system without the need for modifications.

In practice, this means:

• stable communication with the PDC control module,
• preservation of factory sensitivity and range characteristics,
• reduced risk of system errors resulting from improper part matching.

Condition and service application

The parking sensor is a used component, making it an attractive solution for cost-effective repairs where combining functionality with a reasonable budget is key. Such components are often chosen for:

• repairs after minor parking collisions,
• point damage to individual sensors,
• servicing fleet vehicles where quick part availability is essential.

Support for selecting used electronics

When choosing a used PDC sensor, it is worth paying attention to compatibility with the vehicle's installation and system parameters. A detailed discussion on the principles of selecting used modules and sensors, including compatibility and marking issues, can be found in the Global Parts guide: Used automotive electronics – ECU modules and second-hand sensors.
