Technical characteristics of the Audi A4 B9 side window

The described rear right side window has been designed specifically for the Audi A4 B9 generation body, taking into account the geometry of the window frame and factory mounting points. The applied AS3-type tinting limits light penetration into the interior, improving travel comfort for rear-seat passengers and reducing cabin heat buildup. At the same time, the glass maintains clarity and visibility from the inside, which is essential for driving safety.

Function and application in the bodywork

The rear side window on the right side plays an important role in stiffening the body area around the pillar and rear wheel arch, as well as protecting the interior from external factors. A properly selected component:

• ensures tightness within the rear part of the cabin,
• maintains the correct stylistic line of the side bodywork,
• supports acoustic comfort inside the vehicle,
• protects upholstery and trim elements from UV radiation.

Thanks to the factory tinting, the glass blends well with the other rear windows, which is particularly important when replacing a single element after mechanical damage.

Benefits of using original Audi automotive glass

Choosing an original side window for the Audi A4 B9 allows you to maintain compliance with the manufacturer's factory standards. Proper fitment to the door frame or side panel translates into:

• precise fit with seals and trim strips,
• stable seating in the mounting system,
• no need for bodywork modifications or adjustments,
• maintenance of a uniform level of tinting across all rear windows.

Such a solution is particularly beneficial for post-accident repairs and body restoration, where both aesthetics and maintaining performance parameters close to factory specifications are important.

Used condition and informed parts selection

The presented rear right side window belongs to the group of used Audi automotive glass, which allows for a significant reduction in repair costs compared to purchasing a new component. When selecting such a part, it is worth paying attention to the general condition of the glass surface, the absence of serious structural damage, and compatibility with the body version. A used window, sourced from dismantling, can be an effective solution for maintenance repairs, especially when the priority is to maintain the vehicle's original appearance.
