Purpose and fitment

The presented mirror belongs to the Wing Mirrors category and has been designed specifically for the Audi A4 B8 generation. The construction intended for the right side of the vehicle ensures correct geometry, proper field of view, and compatibility with factory mounting points on the door.

The Brilliant Black Metallic LY9B color allows for maintaining a uniform body style line without the need for additional painting, provided the vehicle has the same paint code. This solution is particularly beneficial for post-accident repairs and when replacing components prone to operational damage.

Construction and functional properties

The mirror is an OEM Audi component, which means it maintains factory quality standards regarding fitment, housing rigidity, and weather resistance. The construction intended for the right side of the vehicle guarantees appropriate stability at higher speeds and proper water drainage from the housing surface.

The housing in the Brilliant Black Metallic LY9B shade features an elegant, metallic finish that harmonizes well with the Audi A4 B8 body line. As a result, the mirror not only restores full functionality but also maintains a consistent, aesthetic appearance of the vehicle.

Condition and benefits of choosing a used part

The item is offered as a used part, which represents a reasonable compromise between repair costs and maintaining the original manufacturer's quality. In practice, this means the ability to restore the full functionality of the vehicle's side zone without the need to invest in a new component, while maintaining factory fitment.

Choosing an original, used wing mirror allows you to reduce the risk of installation problems typical of aftermarket replacements, such as inaccurate fitment or differences in paint shade. This solution is particularly recommended for repairs where both correct geometry and visual consistency with the rest of the body are important.
