Purpose and vehicle fitment

The cover has been designed as a mirror component for the left side of the body, maintaining the geometry specific to the Audi A4 B7 generation. This ensures proper adhesion to the mirror glass and adjacent body panels, which reduces gaps and unwanted vibrations while driving.

The Phantom Black - Z9Y color allows for aesthetic integration with Audi's factory paint palette, which is particularly important for spot repairs when visual consistency is required without the need to replace the entire mirror assembly.

Technical and functional characteristics

As a part from the Mirror components group, the housing serves a protective function for the adjustment mechanism and the mirror glass, shielding them from external factors. A properly selected cover reduces the risk of moisture and contaminants entering the mirror body, which helps maintain stable operation of the adjustment components.

The used OEM construction ensures the preservation of the original shape and parting lines relative to the door and pillar, which is significant for both aerodynamics and wind noise levels at higher speeds. Thanks to the factory mounting profile, it is possible to use existing mounting points without the need to modify the mirror body.

Benefits of using the original mirror cover

Using this cover allows for:

• restoring the consistent appearance of the left side of the body after mirror damage,
• maintaining the factory shape and parting lines of body components,
• protecting the adjustment mechanism and mirror glass from external factors,
• reducing the risk of additional vibrations and noise in the mirror area.

For users planning broader work on the side visibility system, this cover can be one of the key elements in restoring full functionality and aesthetics to the driver's side mirror.
