Purpose and function of the component

The presented B-pillar window frame cover is dedicated to the rear left door of the S210 E-Class estate body. The component operates in the immediate vicinity of the door window, responsible for:

• covering the B-pillar structure from the window frame side,
• stable guidance of the window edge during opening and closing,
• maintaining proper pressure of the door seal,
• visually consistent connection of the side window lines in the Avantgarde version.

Thanks to the factory fit, the cover allows for maintaining the correct geometry of the door frame, which translates into reduced wind noise and proper seal adhesion.

Compatibility and body fitment

The cover has been designed specifically for the rear left door of the S210 body, which means precise fitment to the shape of the window frame and factory mounting points. The lack of need for modifications or on-site adjustments shortens work time and reduces the risk of leaks.

As an original Mercedes part, it maintains compatibility with the styling line of the Avantgarde package, ensuring that after replacement, there are no differences in shade, profile, or texture compared to other elements of this body zone.
