Purpose and function in the vehicle

The presented PDC sensor is designed to work in both the front and rear body zones, allowing for consistent operation of the entire parking system. The placement on the vehicle covers the front and rear area, which allows the component to be used as a replacement in various mounting positions in the bumper, according to the configuration of a specific Mercedes W176 unit.

The component works with the factory electrical installation and the parking system controller, ensuring stable signal transmission from the obstacle to the control module. Thanks to this, the driver receives clear acoustic or visual information about the distance from an object, which facilitates maneuvering in tight spaces.

Color scheme and visual fit

The sensor features a finish in the Polar White - 149 shade, which allows for aesthetic integration into the vehicle's painted body elements. This color scheme minimizes the visibility of the component on the bumper, maintaining a consistent look of the body lines and reducing the need for additional painting.

Thanks to the factory finish, the sensor fits well into the styling of Mercedes models, ensuring visual compatibility with original components installed on the production line.

Technical characteristics and installation

As a component from the Parking sensors category, the product is adapted to work in a demanding external environment – in a zone exposed to moisture, temperature changes, and road dirt. The housing design allows for installation in the bumper socket intended for factory PDC sensors, which facilitates service and shortens replacement time.

The sensor is a used component, which in practice means it comes from disassembly and has been verified for suitability for further use. This type of component allows for an economical repair of the parking system while maintaining the original mounting and electrical specifications.

Application in the Mercedes PDC system

Mercedes W176 Front Rear Bumper Parking Sensor PDC Polar White works with the factory PDC system, responsible for generating a feedback signal based on the reflection of the wave from an obstacle. A properly functioning sensor is crucial for:

• accurate determination of the distance from obstacles during parking,
• reducing the risk of damage to bumpers and body elements,
• increasing the comfort of maneuvering in urban traffic,
• maintaining full functionality of driver assistance systems.

Replacing a damaged component with an original PDC sensor allows you to restore the proper operation of the entire system without the need for interference with the vehicle's installation or software, provided that the other components of the system are functional.

Why choose a used Mercedes PDC sensor

In the case of body electronics, such as parking sensors, choosing a used OEM component is often a reasonable compromise between cost and maintaining factory operating parameters. An original sensor from disassembly ensures:

• compatibility with the installation and controller in a given Mercedes model,
• factory dimensional fit to the mounting socket,
• visual consistency with the body paint in a specific color.
