Purpose and fitment for Audi A6 C6

The presented window is dedicated to the rear part of the body on the left side, which guarantees a proper fit to the door structure of the Audi A6 C6 generation in the saloon version. Thanks to the factory edge profile and the appropriate bending radius, the glass works with the original guides, seals, and window lifting mechanism, ensuring smooth operation and system tightness.

Characteristics of AS3 tinted glass

Glass marked with the AS3 class is a solution used in the area of rear windows, where darker tinting is permitted. This type of window:

• reduces the amount of sunlight reaching the interior,
• limits cabin heating on sunny days,
• increases visual comfort for passengers,
• improves the privacy of the rear part of the vehicle.

The black tint gives the body a more cohesive, toned-down look, blending well with the side line of the Audi A6 C6 and factory trim elements.

Practical application and benefits of installation

Installing the rear left door window in the tinted version is particularly beneficial in the case of:

• post-accident repairs and replacement of damaged glass,
• restoring full functionality of the window lifting mechanism,
• replacing a missing element after disassembly or theft,
• maintaining a consistent appearance of the side window line on one side of the vehicle.

Original glass dedicated to a specific model minimizes the risk of leaks, rattles, or improper guide operation, which translates into stable operation and predictable behavior of the element over a long period.

Condition, origin, and OEM quality

The window comes from disassembly and is offered as a used part, which allows for a significant reduction in repair costs while maintaining the characteristics of the original Audi equipment. The factory geometry and glass structure are preserved, allowing the element to be used both in body and glass repairs and in restoring the original vehicle specification.

Support with selection and related technical information

When selecting a window, it is worth paying attention to the mounting side, body type, and compatibility with vehicle equipment to maintain full door functionality and user comfort. If necessary, you can refer to the manufacturer's markings and catalog numbers, which facilitate verification of compatibility with a specific version of the Audi A6 C6.
