Purpose and fitment for Audi A4 B7

The presented mirror belongs to the Exterior mirrors category and was designed specifically for the Audi A4 B7 body. The support structure, mounting method to the door, and the angle of the housing are consistent with the manufacturer's factory specifications, which facilitates installation and helps maintain the original side profile of the car. Its placement on the right side of the vehicle ensures proper blind-spot coverage and compliance with the homologation intended for this model.

Brilliant Red Y3J color and visual aspect

The mirror is finished in Brilliant Red Y3J, a color characteristic of the Audi paint palette. As a result, the component integrates well with a body of the same shade, reducing the need for additional painting when replacing a damaged mirror. Color consistency helps maintain the aesthetics of the side bodywork, which is important both for post-accident repairs and when preparing the car for sale.

Structural and functional parameters

The mirror is designed as a complete housing with a support section, adapted for installation in the factory mounting points of the Audi A4 B7 door. The applied structural solutions ensure:

• stable positioning of the mirror at higher speeds,
• appropriate housing rigidity in the mounting zone,
• correct routing of cables inside the door (in accordance with the factory installation layout).

Additionally, the housing geometry has been selected to reduce air turbulence and cabin noise, which translates into a more comfortable driving experience on the road.

Condition, origin, and service application

The item comes from the Audi line and is an OEM part, which means it maintains factory manufacturing standards and compatibility with the A4 B7 body. The used nature of the product makes it a beneficial solution for post-accident repairs, where the priority is combining technical correctness with cost control. The mirror is suitable for both body and paint shops as well as independent workshops specializing in the Audi brand.
