Purpose and compatibility with Audi A4 B8

The presented mirror has been designed specifically for the Audi A4 B8 generation, taking into account factory mounting points and the characteristic body lines. Its placement on the left side of the vehicle guarantees compatibility with the door and pillar construction, as well as the correct positioning of the mirror glass relative to the driver.

By maintaining the original housing shape and the correct tilt angle, the mirror supports safe blind-spot monitoring and improves visibility of the situation in the adjacent lane. This is particularly important when driving in urban traffic and on high-speed roads.

Sphere Blue Metallic – X5X color and body aesthetics

The mirror is finished in Sphere Blue Metallic – X5X, a color characteristic of the Audi paint palette. The metallic coating gives the body a cohesive, modern look and reduces the need for additional painting when replacing the component with one in the same shade.

Choosing a mirror in the correct factory color makes it easier to maintain the vehicle's uniform aesthetics, which is important both for daily use and for the potential resale of the car. This is a practical solution when you want to quickly restore the original appearance of the side body section.

Electric control and functionality

The mirror belongs to the Door Mirrors group with electric control, which allows for convenient adjustment of the mirror glass position from inside the vehicle. This type of solution improves ergonomics, especially when the car is used by several drivers with different seating positions.

The electric adjustment drive works with the factory Audi installation, which allows for full functionality to be maintained without the need for wiring or switch modifications. This is important from the point of view of durability and subsequent diagnostics of the electrical system.

Characteristics of the used component

The offered mirror is a used item, which allows for lower repair costs while maintaining the original manufacturer's specifications. This type of component is particularly beneficial for post-accident repairs, where combining correct fitment with a reasonable budget is key.

Choosing an original, used door mirror instead of an aftermarket replacement promotes the preservation of factory-quality fitment with the door, as well as compatibility with other body and electrical system components.

How to verify compatibility by OEM number

To ensure full compatibility with your Audi A4 B8, it is worth comparing the OEM number and interchangeable numbers with the data in the vehicle's technical specifications or service documentation. In case of doubt, matching by VIN number may also be helpful.
