Intended Use and Function of the Part

The described mirror base belongs to the Exterior Mirrors category and is dedicated to left-side Mercedes C-Class W204 models. The element forms the structural skeleton of the complete mirror – it is responsible for the correct positioning of the housing, mirror glass, and the electric folding assembly. A properly selected base eliminates play, vibrations, and incorrect mirror alignment relative to the door.

Construction and Body Fitment

The base has been designed for specific mounting points in the Mercedes W204 door, allowing installation in existing factory locations without the need for bodywork modifications. The element's geometry ensures:

• stable connection to the left-side door panel,
• correct mirror angle relative to the driver,
• mounting space for the electric folding mechanism,
• proper routing of the electrical harness inside the mirror.

This maintains the factory ergonomics for observing the vehicle's side area and compatibility with other mirror components.

Electric Folding Function

The base is adapted to work with the electric mirror folding mechanism. This means appropriately shaped space for the actuator, guides, and motion transfer elements. The correct fit of this part is crucial for:

• smooth operation of the folding and unfolding function,
• maintaining end positions without excessive play,
• reducing mechanical loads on the folding motor,
• minimizing noise and vibrations during system operation.

Replacing a damaged base with a functional part allows for the restoration of the correct folding function, which is important both in city traffic and when parking in tight spaces.

Condition, Quality, and Service Application

The offered mirror base is a used part, allowing for economical repair of the exterior mirror area while maintaining original geometry and body fitment. This is a practical solution in cases of:

• damage from a side collision or scraping against an obstacle,
• cracked mirror mounts in the door,
• problems with correct mirror alignment or stability,
• repair of the folding mechanism requiring housing replacement.

Selecting the correct part is facilitated by the manufacturer's marking and its belonging to the Exterior Mirrors category, which minimizes the risk of ordering errors.

Integration with Other Mercedes Mirror Components
