Intended Use and Fit for BMW F21

This part belongs to the group of BMW car glass, ensuring compatibility with the factory body line, as well as with original seals and mounting trims used in this model.

Technical and Visual Characteristics

The presented body glass has a specific placement in the vehicle – the rear left side – which facilitates unambiguous identification when selecting parts. The black finish allows for an aesthetic integration with factory body elements such as frames, pillars, or seals, creating a visually cohesive side area of the car.

The AS3 designation indicates the type of glass used in automotive applications, which is important for performance parameters such as light transmission and layer characteristics. This ensures that the glass can provide an appropriate level of optical comfort and match the other glazing in the vehicle.

Condition, Origin, and Practical Application

The part comes from the used BMW parts group, allowing for an economical replacement of damaged glass while maintaining the original manufacturer's specifications. This type of component is particularly useful in cases of:

• post-accident repairs to the side body section,
• mechanical damage to the glass (cracks, scratches, chips),
• restoring the completeness of glazing after bodywork and painting interventions.

Using an original body glass helps maintain proper structural rigidity within the window opening and reduces the risk of leaks resulting from imprecise fit of aftermarket alternatives.
