Purpose and fitment for Audi Q2 GA

The presented window has been designed specifically as the rear left door side window for the Audi Q2 GA model. Its placement in the rear zone, on the driver's side, ensures full compatibility with the body line, factory seals, and guides, which translates into stable seating and system tightness.

Thanks to a design consistent with the manufacturer's solutions, this component allows for maintaining the vehicle's coherent aesthetics, correct glazing geometry, and proper operation with the window lifting mechanism.

Characteristics of AS3 tinted glass

AS3 standard glass is a solution used in areas where reducing light transmission and improving thermal comfort are priorities. The tinted surface limits interior heating, which is particularly noticeable during the summer season, while simultaneously reducing glare and improving travel conditions for rear-seat passengers.

The tinting also helps protect the interior from fading of upholstery and trim elements, and from the outside, it gives the Audi Q2 GA a more cohesive, modern look, characteristic of versions equipped with extensive optical packages.

Functionality and practical aspects

The rear left door side window plays an important role in terms of safety, comfort, and vehicle ergonomics. It is responsible for:

• maintaining proper lateral rigidity within the door opening,
• cooperation with the window lifting and lowering mechanism,
• protecting passengers from wind, rain, and debris,
• reducing aerodynamic noise while driving.

By replacing a damaged window with an original component of similar specifications, you maintain factory acoustic and optical parameters, as well as the correct operation of seals and guides.

Condition, origin, and benefits of choosing used OEM

The offered window comes from the Audi product line and is a used component, which allows you to combine a reasonable purchase cost with the preservation of original manufacturing quality. In practice, this means a perfect fit for factory mounting points, consistency with the door frame shape, and the correct tinting characteristics.

Choosing a used OEM component is particularly beneficial in the case of premium segment cars, where the visual and technical consistency of the entire bodywork matters. You receive an element with parameters similar to those factory-installed, without the need for compromises regarding fitment.

Comprehensive window replacement in Audi – what else to consider

When replacing the rear left side window, it is worth paying attention to the condition of other glazing, seals, and guides to avoid differences in glass shade and ensure the uniform operation of the entire system. In many cases, it pays to plan work on a broader scale, including other glazing elements.
