Vehicle Application and Placement

The presented window belongs to the Automotive Glass category and is intended for installation in the left front door of the BMW 3 Series G20 generation. Its placement in the front section of the body on the driver's side guarantees proper cooperation with the window lifting mechanism, seals, and the door frame specifically designed for this model.

The AS2 glass type signifies that the window meets the requirements for light transmission and safety for road use. Thanks to its factory-edge profile and appropriate contouring, the component works correctly with the guides and seals, which reduces wind noise and the risk of leaks.

Technical Characteristics of AS2 Glass

Glass designated as AS2 is used in BMW vehicle side windows, providing a balanced level of clarity and UV protection. The window's construction is adapted to homologation requirements, and its thickness and structure are optimized for mechanical strength and resistance to typical operational loads, such as body vibrations or frequent operation of the lifting mechanism.

Due to its factory fit for the BMW G20, the window maintains the correct geometry, which facilitates installation and minimizes the need for additional adjustments. This is particularly important for vehicles equipped with precisely fitted seals and door frames, where minor deviations can cause creaks, wind noise, or increased wear on the guide components.

Condition, Origin, and Benefits of Using a Used Part

The offered window is a used part, sourced from a dismantled BMW vehicle. Choosing original second-hand glass allows for maintaining factory fit and quality parameters while reducing repair costs. For many BMW G20 owners, this is a sensible compromise between quality and budget, especially for post-accident repairs or replacement of damaged glazing.

Using an original door window from BMW ensures visual consistency with other body elements and compatibility with existing seals, guides, and the lifting mechanism. This is the preferred solution for workshops specializing in the BMW brand, which prioritize maintaining the vehicle's factory specifications.

Selection by OEM Number and Purchase Support

This door window has a dedicated OEM part number and associated interchangeable numbers, which facilitates precise identification of the component for a specific equipment version and model year of the BMW G20. When selecting, it is advisable to use the VIN and part number to ensure full compatibility with your vehicle.
