Purpose and function in the vehicle

The sensor belongs to the Parking sensors category and is designed to operate in the front bumper area. It is responsible for generating feedback for the driver during parking, which helps reduce the risk of contact with obstacles and facilitates precise vehicle positioning in tight parking spaces.

Its front-mounted position ensures compatibility with the factory PDC system, maintaining the original system logic and the consistency of acoustic and visual alerts on the instrument cluster or multimedia screen.

Compatibility and fitment

The component is intended for selected models of the W169, W245, W204, and W212 series, allowing for full compatibility with the factory electrical installation and vehicle control units. Using an original sensor minimizes the risk of system errors, calibration issues, and malfunctions of the parking assistance system.

The Obsidian Black Metallic - 197 color facilitates aesthetic installation in bumpers painted in the same shade, minimizing the visibility of the component and maintaining a consistent body appearance. This solution is particularly beneficial for post-accident repairs and when replacing individual sensors in an already painted bumper.

Performance characteristics and installation

As an original part, the sensor is structurally adapted to the factory mounting sockets in the bumper, which simplifies installation and allows for the use of existing brackets and wiring harnesses. As a result, the installation process is efficient, without the need for mechanical or electrical modifications.

Used condition means that the component comes from dismantling, which in practice allows for combining a favorable purchase cost with the preservation of the manufacturer's original specifications. This is a solution often chosen for servicing PDC systems in older vehicles, where both functionality and repair economy are important.

Benefits of using an original PDC sensor

• Consistent cooperation with the factory parking assistance system in Mercedes vehicles.
• Reduced risk of diagnostic errors and PDC failure messages.
• Color matching in Obsidian Black Metallic - 197, improving bumper aesthetics.
• Ability to use existing brackets and harnesses without additional modifications.
• A reasonable compromise between repair cost and maintaining original quality.
