Purpose and fitment

The presented window glass is dedicated for installation in the rear left section of the body, in the passenger door on the driver's side. Thanks to the preservation of the original edge geometry and correct arc profile, the component works with factory guides, seals, and the door frame, minimizing the risk of leaks and improper operation of the window lifter.

The AS2 marking indicates the appropriate level of tinting and light filtration, consistent with the requirements for side windows, which translates into driving comfort and compliance with homologation regulations.

Performance parameters and safety

The glass has been manufactured using technology intended for side door windows, ensuring controlled breakage characteristics and proper resistance to operational loads. The construction is adapted to operate in variable temperature conditions typical for the European climate, which limits the risk of thermal stress.

Thanks to its factory origin from the Volkswagen group, compatibility is maintained with:

• original door perimeter seals,
• the window lifting and lowering mechanism,
• factory mounting points in the regulator arm.

Such fitment facilitates installation and allows for maintaining the proper level of acoustic sealing and water protection.

Characteristics of the used product

The item comes from the used parts category, which is a beneficial solution for users looking for original components while maintaining reasonable repair costs. Unlike many aftermarket replacements, the dismantled glass retains factory shape and thickness parameters, which is important for precise positioning in the guides and door adjustment.

Choosing an original used window glass often allows you to avoid fitment problems typical of cheaper replacements, while simultaneously maintaining the visual consistency of the vehicle's glazing.

Benefits of using an original Volkswagen window glass

Using this glass in the rear left door translates into several practical benefits:

• Factory fitment – no need for modifications to the door frame or guides.
• Consistent glazing optics – similar level of tint and color compared to other windows in the vehicle.
• Stable operation of the lifting mechanism – proper weight and geometry limit the load on the regulator.

For users who plan to keep their car in good technical condition for a longer time, choosing an original glass from the Car windows group is a more predictable solution than installing a random replacement.
