Purpose and function of the component

The presented cover cap is dedicated to the headlight washer system in the Mercedes W164 model and is mounted on the left side of the vehicle. It is responsible for the aesthetic covering of the nozzle opening in the bumper and provides stable guidance for the extending washer arm. Thanks to its precise profile and fit to the shape of the bumper, the component ensures the correct operation of the mechanism, limits the ingress of contaminants, and helps maintain even distribution of fluid on the headlight surface.

Color and visual fit

The cover cap is finished in Obsidian Black Metallic, consistent with the factory Mercedes paint code. This allows for seamless integration of the component into the body line without the need for additional painting, provided the vehicle has the same color code. The metallic coating provides the characteristic depth and gloss, ensuring that after installation, the uniform aesthetics of the front bumper and headlights are maintained, which is important both for accident repairs and when replacing individual exterior components.

Technical characteristics and installation

The cover cap is an OEM component from the Washer fluid reservoirs, pumps and nozzles group, which means it complies with factory mounting geometry and the shape of the working surface. This facilitates installation in place of the original part without the need for modifications to the bumper or the washer mechanism. The product is in used condition, which in practice means it may show signs of wear typical for body components, but it retains the functionality and shape necessary for the proper operation of the system.

Due to the preservation of the original design, after correct installation, the cover cap works with the extending washer arm, does not block its movement, and does not cause stress in the mechanism. This is especially important in vehicles equipped with xenon or LED headlights, where a functional washer system is essential for safety and regulatory compliance.

Application in repairs and body restoration

The component is suitable both for replacing a damaged or lost cover cap and for comprehensive front-end repairs after a collision. A used, original component allows for cost savings compared to a new part, while maintaining the correct fit to the bumper and headlight. This is a practical solution for body shops and individual users who want to restore the factory look of the vehicle without compromising on compatibility.
