Purpose and Body Fitment

The offered window is designed for installation in the rear left door, which guarantees correct positioning in the door frame and proper cooperation with the window regulator. The part is dedicated to Audi A8 and S8 models, ensuring compatibility with the body line, seals, and the factory glass guide system.

The double window construction (double window) promotes stable guidance in the tracks, reduces vibrations, and improves sealing in the rear passenger cabin area. This is particularly important in premium cars where a quiet interior and repeatable mechanism operation are expected.

Technical Characteristics of the Glass

The window belongs to the AS2 designation group, which in practice means the use of glass with parameters suitable for the vehicle's side glazing. This type of glass provides good clarity, resistance to typical operational loads, and compliance with homologation requirements for side windows.

The double rear window helps maintain a stable interior temperature and reduces noise penetration from the outside, which is particularly noticeable for rear passengers. This allows the Audi A8 / S8 cabin to maintain comfortable acoustics even at higher speeds.

Condition of the Part and Benefits of Choosing a Used Part

The offered window is a used original part, which in practice means retaining the factory shape, geometry, and compatibility with the Audi body. Choosing a second-hand part allows for reduced repair costs while maintaining a high level of vehicle fitment.

Practical Application in Service and Repairs

When replacing the rear side window in an Audi A8 / S8, it is crucial to use a part with the correct type of glass and proper placement on the vehicle. The presented window has been prepared for installation on the rear left side, which facilitates service work and minimizes the risk of door closing problems, leaks, or improper regulator operation.

In practice, this means that after correct installation, the window should move smoothly in the guides, maintaining even pressure against the seals and a stable position in any position. This is important both from the perspective of passenger comfort and protection of the interior from moisture and noise.
