Purpose and function of the window

The presented window is a component mounted in the rear left part of the body, in a fixed frame. This type of component is responsible for:

• maintaining the lateral rigidity of the body structure,
• proper illumination of the rear part of the cabin,
• protecting passengers from wind, rain, and external contaminants.

Thanks to the tinted finish in the AS3 standard, the window helps reduce sunlight penetration into the interior, which promotes a more stable cabin temperature and improves travel comfort in the back seat.

Technical and visual characteristics

The window has been designed specifically for the BMW F48 series body, taking into account the body geometry and the side line characteristic of this generation. The black edge ensures an aesthetic connection with seals and trim elements, and also masks the bonding zones from the interior of the vehicle.

Tinting in the AS3 standard means increased reduction of light transmittance compared to front windows, which is typical for rear windows in many BMW models. This solution improves visual comfort for passengers and limits the visibility of the vehicle interior from the outside.

Condition of the item and benefits of using a used part

The offered window comes from the secondary market, which allows for combining a reasonable purchase cost with maintaining factory fitment to the body. A used OEM component is a good solution in a situation where mechanical damage or window breakage has occurred, and the priority is to maintain the original vehicle specification.

Using a window from disassembly allows for:

• maintaining a consistent tint shade relative to the other windows,
• preserving the original geometry and thickness of the glass,
• reducing repair costs compared to purchasing a new component.

Compatibility and part selection

To correctly select the window for a specific BMW F48 unit, it is worth paying attention to aspects such as the body version, production year, and side window configuration. OEM markings and interchangeable numbers allow for verifying the compatibility of the component with the specific vehicle specification, which minimizes the risk of installation problems.
