Purpose and fitment for Audi A4 B9

The rear left quarter window glass has been designed specifically for the Audi A4 B9 generation, maintaining factory curves and body geometry. Its placement in the rear left part of the vehicle guarantees a proper fit with the door frame or fixed body panel, without the need for modifications or forced adjustments. The original glass construction allows for:

• maintaining the factory side body line,
• proper cooperation with seals and trim strips,
• stable seating in the body, reducing unwanted vibrations.

Technical characteristics of the AS2 glass

The AS2 marking indicates glass with appropriately selected light transmission, compliant with the requirements for side windows in modern passenger cars. This type of glass provides:

• comfortable interior illumination while reducing glare,
• adequate mechanical strength in daily use,
• consistency with other factory-fitted windows in the Audi. By maintaining the manufacturer's standards, the glass works with factory mounting elements, which facilitates service work and shortens replacement time.

Benefits of using original used glass

Choosing a used OEM component from the Car windows category is a solution that allows you to combine cost control with high-quality fitment. In practice, this means:

• factory dimensions and shape, eliminating assembly problems,
• consistent appearance of the side body after repair,
• preservation of the correct optical parameters of the glass. Used body glass is particularly beneficial for post-accident repairs or spot body restoration, where technical compliance with the original at a reasonable budget is a priority.

Professional application and installation tips

The rear left quarter window glass for Audi has been prepared for installation in service or workshop conditions. When replacing, it is recommended to:

• thoroughly clean the contact surface on the body,
• check the condition of the seals and replace them if necessary,
• verify the correct adhesion of the glass around the entire perimeter after installation. This approach allows you to maintain body tightness, reduce wind noise, and ensure the durability of the repair.
