Purpose and function in the vehicle

The described base is a component from the Exterior Mirrors group and is responsible for the rigid connection between the mirror housing and the door panel on the left side of the vehicle. The structure is prepared for integration with the auto-dip system, which enables the mirror to tilt automatically during reversing maneuvers, improving visibility of the curb and the rear wheel area.

Proper alignment of the mounting geometry with the Mercedes CLA C117 body reduces stress on the door area and minimizes the risk of mirror vibration at higher speeds. This translates into a clearer image in the mirror and more comfortable vehicle operation.

Mounting parameters and fitment

The base is designed for installation on the left side of the vehicle, ensuring compatibility with the factory mounting hole layout and the mirror's electrical wiring routing. The arrangement of the mounting points has been designed for the specific structure of the CLA C117 door, so that after correct installation, the component creates a tight and stable connection with the panel.

The Cosmos Black Metallic color allows for aesthetic matching to the bodywork in the same shade, reducing the need for additional paint work or limiting it solely to potential minor corrections. This is a practical solution when replacing a damaged mirror base after a collision or service intervention.

Performance characteristics of the used component

As a used component, the mirror base retains its original geometry and factory mounting points, which facilitates trouble-free installation in place of the damaged part. This type of component is particularly beneficial for post-accident repairs, where maintaining compliance with the factory design and optimizing service costs is essential.

Using an original base from the same model series helps reduce the risk of issues with fitting the mirror housing, glass, and adjustment mechanism. This is especially important in vehicles equipped with the auto-dip function, where correct mirror positioning is crucial for maneuvering comfort.

Color and body aesthetics

The Cosmos Black Metallic finish is consistent with the factory paint palette used on the Mercedes CLA C117. As a result, the base integrates well with the body line, maintaining the characteristic, dynamic look of the vehicle's side. With proper installation, uniform gaps and a harmonious transition between the door and the mirror assembly are achieved.

Such color matching is particularly important in cars where maintaining a uniform body aesthetic after body and paint repairs is a priority. A properly selected mirror base helps minimize the visibility of service interventions and maintain a consistent vehicle appearance.
