Purpose and fitment

The presented window glass is dedicated to the rear left body section of the BMW E66, which guarantees compatibility with the factory door construction and proper operation with the window regulator mechanism and seals. As a result, installation is straightforward, with no need for modifications or edge adjustments.

Its original BMW origin ensures the correct profile, thickness, and geometry, which translates into stable seating in the door frame and proper adhesion to the seals when closed.

Technical specifications and workmanship

The glass belongs to the AS3 marking group, which in practice means a special type of automotive glass that provides appropriate performance parameters in the rear part of the vehicle. The material used is adapted to operate in varying temperature conditions and to work with factory guides and mounts.

The black finish on the edge of the glass allows for an aesthetic connection with the door frame and upholstery elements, creating a visually cohesive window outline. This solution also limits the visibility of any mounting elements from the interior side.

Vehicle function and benefits of installation

Replacing a damaged rear left window with an original BMW E66 component allows you to restore:

• proper protection of the interior against weather conditions,
• correct structural rigidity within the door area,
• acoustic comfort in the rear part of the cabin,
• a cohesive look of the side body line.

Using a pre-owned OEM component is also a reasonable compromise between repair costs and maintaining factory parameters, without the need to resort to aftermarket replacements with uncertain fitment.

Condition and service application

The glass comes from dismantling, which allows for the use of an original component in the process of post-accident repairs or when replacing a mechanically damaged part. This type of part is particularly useful in professional body shops and workshops specializing in the BMW brand, where compliance with factory specifications is essential.

Thanks to the preservation of the original geometry, it is possible to efficiently set the glass in the guides and ensure proper cooperation with the existing lifting mechanism, which reduces adjustment time after installation.
