Purpose and body fitment

The presented window has been constructed as a component dedicated to installation in the rear left door, ensuring proper alignment within the door frame and correct operation with the window regulator mechanism. Thanks to the factory edge profile and the appropriate curvature radius, the glass maintains the side line of the body, ensuring a consistent appearance and proper sealing against the weatherstrips.

Proper fitment within the door zone translates to reduced wind noise, correct water drainage, and stable operation of the guides. This is particularly important during daily vehicle use, when the window is raised and lowered frequently.

Technical characteristics of the AS2 glass

The AS2 type glass belongs to a group of windows with specific light transmission parameters and mechanical resistance, commonly used in modern door constructions. The applied automotive glass technology ensures:

• adequate resistance to stresses resulting from the operation of the lifting mechanism,
• dimensional stability within the door frame,
• compliance with required safety standards for side windows.

As a result, the glass can be directly integrated with existing door hardware, such as guides, seals, or mounts, without the need for additional modifications.

Benefits of using original Audi glass

Choosing a component from the Audi production line translates into a number of practical advantages in daily vehicle operation. The most important include:

• Factory fitment – the glass was designed for the specific geometry of the door, which facilitates installation and minimizes the risk of leaks.
• Compatibility with existing hardware – compatibility with factory guides, seals, and the window regulator mechanism is maintained.
• Visual consistency – the shade and character of the glass are adapted to the standards used in the given model, which allows for maintaining a uniform appearance of the entire side glazing area.

Such a solution is particularly beneficial for post-accident repairs or replacing damaged glass, where the priority is to maintain the original character of the vehicle.

Used glass as an economical service solution

The item comes from the used parts group, which allows for a significant reduction in repair costs while maintaining the parameters typical of OEM components. In many cases, salvaged windows are chosen as a reasonable alternative to new parts, especially when the priority is to optimize the service budget while maintaining factory fitment.
