Purpose and fitment for Audi A4 B9

The presented window is dedicated to the Audi A4 B9 model and has been designed as a component for the rear right part of the body. The vehicle placement specified as rear – right side means that the window works with factory mounting points, seals, and trim, which facilitates installation and allows for maintaining the original body line.

Proper dimensional and shape matching reduces the risk of glass stress, leaks, and unwanted wind noise when driving at higher speeds. This is particularly important when replacing glass elements in modern bodies, where assembly tolerances are very precise.

Technical and functional characteristics

The window belongs to the Car windows group, which means it meets the requirements for mechanical strength and resistance to operating conditions typical for body glass elements. The use of the appropriate grade of glass ensures:

• dimensional stability and proper structural rigidity within the body frame,
• appropriate light transmission consistent with the purpose of the rear side window,
• proper cooperation with seals and finishing elements.

Positioning on the vehicle as a rear right body component means that the window affects the lateral rigidity of the body and the comfort of rear-seat passengers, reducing outside noise and improving interior insulation.

Condition of the component and use in repairs

The offered window is a used component, which makes it a cost-effective solution for post-accident repairs, replacing damaged windows, or body reconstruction on a controlled budget. A used original component allows for maintaining visual and technical consistency with other body parts while reducing expenses compared to a new part.

In practice, such a window will work well both in professional body and paint shops and in workshops specializing in Audi vehicle repairs, where precise fit and maintaining factory body parameters are essential.
