Purpose and vehicle placement

The presented window is intended for installation in the rear left part of the body, within the side bodywork area. It is responsible for illuminating the rear of the cabin and maintaining the structural rigidity of the side panel. Thanks to its precise profile and curvature, it fits factory seals and the body frame, which facilitates installation and reduces the risk of leaks.

The placement in the vehicle is precisely defined as rear – left side, which minimizes the risk of errors when selecting parts and allows for efficient planning of bodywork and glass repair tasks.

Technical and functional characteristics

The AS2 type body window belongs to a group of elements ensuring proper transparency and optical comfort inside the vehicle. The applied automotive glass technology guarantees:

• stable seating in the body frame using standard mounting systems,
• adequate resistance to stresses resulting from bodywork operation,
• consistent appearance with other glazing elements in the Audi A1 8X.

Thanks to maintaining the factory shape, the window works with original seals and trim strips, which limits the need for additional modifications during repair.

Condition of the component and use in repairs

The offered window is a used part from disassembly, which allows combining reasonable repair costs with maintaining the manufacturer’s original specifications. This type of part is particularly suitable for:

• accident repairs of the rear body section,
• replacing a window after cracking, scratching, or shattering,
• completing missing elements during vehicle restoration.

Using an original window from the same model line allows for maintaining the visual consistency of the vehicle and proper fitment with body components.

Benefits of using an original Audi window
