Purpose and function of the component

The right mirror cover is responsible for protecting the mirror glass and adjustment mechanism from external factors such as water, dirt, or minor impacts. Thanks to its precise fit to the BMW F20/F21 series body structure, proper aerodynamics and stable mounting of the entire mirror assembly are maintained.

This component is particularly important for repairs following side collisions or parking damage, where it is necessary to replace only the cover without interfering with the other mirror components.

Technical parameters and fitment

The presented cover belongs to the BMW External mirrors group and is intended for installation on the right side of the vehicle. The design has been engineered to work with the factory mirror mount in BMW F20/F21 models, which facilitates installation and eliminates the need for additional modifications.

The black color of the cover allows for maintaining a subdued, consistent body style or serves as a good base for potential painting to match a specific vehicle paint code. As a result, this component can be used both for restoration repairs and subtle visual modifications.

Condition of the component and benefits of use

The mirror cover is offered as a used part, which allows for an economical repair while maintaining the manufacturer's original specifications. Choosing an original component from the secondary market reduces the risk of fitment issues typical of universal aftermarket replacements.

Using this cover enables:

• restoring full functionality of the right external mirror after mechanical damage,
• maintaining the factory appearance of the side body of the BMW F20/F21,
• reducing repair costs by replacing only the cover instead of the complete mirror assembly.

Installation tips and selection by numbers

Before installation, it is recommended to compare the shape and mounting points with the currently installed cover to confirm full structural compatibility. Verification by part numbers and interchangeable numbers additionally ensures that the selected component matches the specific mirror configuration of your BMW.
