Vehicle Application and Placement

The presented body glass is designed for installation in the rear left part of the body, in the passenger door area. This placement is important for both safety and driving comfort – a correctly selected glass stabilizes the door structure, affects cabin sealing, and reduces wind noise.

Thanks to precise fitting for the specific W205 body version, the part works with factory seals, guides, and opening mechanisms, which facilitates installation and reduces the need for additional bodywork modifications.

The part has a dedicated OEM part number and associated interchangeable numbers, which facilitates verification of compatibility with a specific vehicle configuration. When selecting, it is advisable to compare the markings with service documentation or the existing glass to ensure full compatibility with the given equipment version.

Functional Characteristics of Body Glass

As a side body glazing element, the rear left door body glass is responsible for several key functions:

• cooperation with door seals, which contributes to protecting the interior from water and dirt,
• maintaining the appropriate structural rigidity of the door in conjunction with the frame and fittings.

A correctly selected glass from this group of elements allows for the restoration of the vehicle's original performance parameters after mechanical damage or replacement of corroded or deformed body parts.

Condition, Installation Advantages, and Repair Application

The offered glass is a used part, which represents a favorable compromise between repair cost and maintaining the original manufacturer's specifications. In practice, this means the possibility of an economical replacement of damaged glass while maintaining the factory standard of execution.

The main advantages of using original, used body glass for this model include:

• factory fit to the rear left door structure,
• maintaining consistency with the styling line of the W205 series body,
