Purpose and Fitment

The presented window is designed as a component for installation in the front left door (driver's side) of the BMW F20 body style. Thanks to its construction conforming to factory BMW standards, proper dimensional tolerances are maintained, facilitating installation in the guides, ensuring correct sealing, and enabling compatibility with the original window regulator.

The AS2 designation indicates the use of an appropriate class of laminated or tempered glass (depending on its position in the vehicle) with proper light transmission, compliant with homologation requirements for side windows in passenger cars.

Glass Characteristics and Color

The window features a green tint, typical for many BMW models, which helps maintain visual consistency with the other windows in the vehicle. This type of tint reduces interior heating, improves visual comfort for the driver and passengers, and minimizes glare during everyday use.

As a product from the Automotive Glass category, it meets requirements for resistance to mechanical stress and temperature changes, which is crucial for the frequent raising and lowering of the window in the driver's door.

Condition, Origin, and Benefits of Using OEM

This window is a used part, sourced from a dismantled BMW vehicle, which preserves its factory fit and geometry. Using an original OEM window reduces the risk of door closing issues, leaks, or improper operation of the lifting mechanism compared to many low-quality aftermarket replacements.

Function in the Vehicle and Installation Aspects

The placement of the window in the front left door area means it is responsible not only for visibility but also for:

• proper interaction with the exterior mirror and A-pillar,
• sealing the cabin against water and noise,
• stable operation within the guides during frequent opening and closing,
• maintaining the original side body line of the BMW F20.

During installation, it is recommended to check the condition of the door seals, guides, and the window regulator mechanism to fully utilize the properties offered by the original door window.
