Purpose and fitment for Audi A4 B8

The presented mirror belongs to the Exterior Mirrors category and has been designed specifically for the Audi A4 B8 generation. Its placement on the left side of the vehicle indicates driver-side installation, maintaining the correct geometry, viewing angle, and factory body lines. The OEM construction ensures compatibility with factory mounting points and electrical wiring, facilitating installation in place of a damaged component.

Functionality: power folding and ease of use

The mirror is equipped with a power-folding function, allowing for convenient folding from the cabin, e.g., when parking in tight spaces or garages. The integrated electric motor works with the factory controls in the Audi A4 B8, allowing operation via the original door switches. This solution improves daily ergonomics and reduces the risk of accidental mirror damage in tight parking lots.

Brilliant Black Metallic – Y9B finish

The mirror housing comes with a factory Brilliant Black Metallic – Y9B finish, characteristic of the Audi paint palette. The metallic black ensures consistency with a vehicle of the same color code, without the need for additional painting. This is a particularly beneficial solution for quick replacements of damaged mirrors when maintaining a uniform aesthetic without extra paint work is a priority.

Characteristics of the used component

The offered mirror is a used component, sourced from vehicle dismantling, which allows you to combine original build quality with a more favorable purchase cost. Such OEM components retain their factory construction, making them a preferred choice for both workshops and individual users looking for parts with proven compatibility. A used exterior mirror is also a solution that reduces vehicle downtime – the part can be installed without waiting for the production or painting of a new component.

Application in repairs and upgrades

The Audi A4 B8 left exterior mirror is suitable for standard replacements following collisions or parking damage, as well as for upgrading the vehicle to a version with power folding. Due to its adherence to factory specifications, it is the right choice in situations where reliable fitment and proper operation of the adjustment system are the priority. In the case of extensive body repairs, it can be part of a wider range of work on the side zone of the vehicle.
