Technical characteristics and intended use

The presented quarter glass has been designed specifically for the Audi A4 B9 generation model, intended for the rear left side of the vehicle.

Thanks to the factory edge profile and appropriately selected glass thickness, the installation process is predictable for an experienced body and paint shop.

Benefits of using an original quarter glass

Using an original quarter glass in an Audi A4 B9 brings a number of practical advantages, important both from the user's and the workshop's point of view:

• factory fit to the bodywork – no need for modifications or edge adjustments,
• preservation of the original structural rigidity of the side body section,
• proper compatibility with original seals and finishing moldings,
• consistent visual appearance with the vehicle's other windows,
• easier valuation and handling in workshops specializing in the Audi brand.

Thanks to this, the glass represents a functional and economical solution for post-accident repairs, bodywork corrections, or restoration of the side body section.

Part condition and use in service practice

• post-accident repairs of the rear left body section,
• restoration of vehicles where the side window has been damaged or cracked,
• restoring the factory look of the car after unprofessional modifications.

Proper selection of the glass for the specific Audi A4 B9 body version minimizes the risk of installation problems and allows for maintaining the structural integrity of the vehicle.

Compatibility, identification, and brand

The offered glass comes from a line of parts intended for Audi, which guarantees compliance with the brand's factory standards. Identification is based on technical data assigned to the product, such as manufacturer markings, part numbers, and interchangeable numbers visible in the specification section. This allows the workshop to easily verify whether the glass will be suitable for a specific body version and model year.
