Purpose and Function of the Component

This external left rear window seal strip is tailored to the BMW U06 series body and is installed on the rear section on the driver's side. It is responsible for stable window guidance, limiting the ingress of water and dirt into the door interior, and reducing noise generated at higher speeds.

Thanks to its factory profile and appropriate rigidity, the strip works in conjunction with the window lifting mechanism, reducing the risk of vibrations and unwanted play. This is particularly important when frequently using the rear windows, for example, in family or fleet vehicles.

High-Gloss Finish and Body Aesthetics

The component features a high-gloss finish, characteristic of BMW styling packages. This allows for consistency with other trim strips around the windows and the vehicle's side line, which is important both visually and for potential resale value.

The appropriately designed profile of the strip conceals the metal edge and seals, creating a uniform line between the window and the door panel. Replacing a worn or damaged part with an original strip eliminates typical signs of wear, such as scuffs, discoloration, or leaks along the bottom edge of the window.

Benefits of Using an Original BMW Seal Strip

Using an original seal strip on the left rear section of the BMW U06 body ensures:

• factory fit to the shape of the door and window,
• proper cooperation with the window lifting mechanism,
• maintained seal integrity at the window-to-door panel contact area,
• a cohesive look with other high-gloss trim elements.

This solution is particularly beneficial for accident repairs, replacement of corroded or deformed parts, and for the visual restoration of the vehicle's side body.

Condition, Installation, and Fitment

The seal strip is offered in used condition, allowing for economical repair while maintaining original BMW specifications. The component is intended for installation on the left rear part of the vehicle, replacing the factory external window strip. With proper installation, factory gaps and the sealing line to the window are maintained, reducing the risk of air noise.

Before installation, it is recommended to inspect the condition of the window guides and other seals in the door to fully utilize the sealing and acoustic properties of the newly installed strip.
