Application and vehicle function

The offered sensor is designed for installation in W204 series models, where it is responsible for accurate obstacle detection in the front and rear zones. Operation in two areas of the vehicle body allows for consistent performance of the factory parking system, providing the driver with clear feedback while maneuvering in tight parking lots, underground garages, or during parallel parking.

The placement on the vehicle includes the front and rear, allowing the component to be used both as a replacement part in an existing installation and when filling a missing sensor in the bumper. This solution helps maintain the uniform operating characteristics of the entire system.

Color and visual matching

The sensor is finished in the Horizon Blue Metallic shade, which allows for harmonious integration with the vehicle's body paint marked with code 391. Thanks to this, after installation, the element does not visually stand out from the bumper surface, and the parking zone maintains a consistent, factory look.

Such color matching is particularly important in premium class vehicles, where not only functionality but also the aesthetics of details matter. Replacing a damaged sensor with an element in the correct color avoids additional painting and shortens repair time.

Technical characteristics and vehicle integration

The presented element belongs to the Mercedes parking sensors group, which means it has been designed to work with the factory electrical installation and control units used by this brand. This enables proper communication with modules responsible for acoustic and visual signaling, without the need for additional adapters.

The product has a dedicated OEM part number and associated replacement numbers, which facilitates the selection of the correct variant for a specific vehicle configuration. Before purchasing, it is recommended to verify compatibility using the VIN or the currently installed part to ensure full hardware and software compatibility.

Condition, purpose, and benefits of installation

The sensor is offered as a used item, which allows for an economical repair of the parking system while maintaining the manufacturer's original specifications. This type of solution is particularly beneficial for older vehicles, where the priority is reasonable service costs while maintaining proper functionality.

Replacing a faulty sensor with a functional component from the same group allows you to:

• restore the proper operation of the parking assistant in the front and rear axle,
• minimize the risk of damage to bumpers and body components during maneuvering,
• maintain a consistent bumper appearance thanks to the Horizon Blue Metallic color match.

Selection, installation, and technical support

To select the right sensor for a specific W204 unit, it is worth using the OEM number or replacement numbers and comparing the placement on the vehicle. Proper identification of the element reduces the risk of installation errors and problems with communication with the vehicle's electronics.

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