Purpose and fitment

The presented glass has been designed specifically for installation in the rear left door of the vehicle, which ensures proper fitment to the door frame, seals, and lifting mechanism. This maintains the correct glass geometry, airtightness, and acoustic comfort inside the cabin.

The AS3 marking indicates a specific type of glazing that meets the required safety and transparency standards used in the automotive industry. The glass is properly contoured for the estate body, which allows for maintaining the consistency of the side line and the aesthetics characteristic of Mercedes models.

Performance and functional parameters

The placement on the vehicle in the rear left part of the body means that the glass operates in a demanding area – exposed to temperature changes, vibrations, and frequent opening and closing of the door. The component's construction is prepared to work with the factory lifting mechanism, guides, and seals, which facilitates installation and subsequent operation.

Selecting glass dedicated to a specific model and side of the vehicle reduces the risk of leaks, excessive stress in the glass, and improper adhesion to the bodywork. This is particularly important for maintaining driving comfort, protection against external noise, and proper water drainage from the door area.

Product characteristics and advantages of use

The element comes from the Car windows group, which means it has been designed with appropriate resistance to mechanical damage and the influence of atmospheric factors in mind. Using an original glass for the rear left door allows for maintaining a uniform shade of glazing on both sides of the vehicle, which is significant both visually and practically.

Key benefits of using this glass include:

• maintaining the factory appearance of the side body section,
• proper fitment to the door frame and seals,
• compatibility with the factory window lifting mechanism,
• maintaining proper visibility and driving comfort for rear seat passengers.

Condition and installation aspects

The product is offered as a used original element, which in practice means a favorable combination of build quality and an attractive price compared to new parts. Choosing an original used glass allows you to maintain compliance with the vehicle's factory parameters while optimizing the costs of repair or replacement of damaged glazing.

During installation, it is recommended to use the services of a workshop experienced in working with body glazing to ensure proper positioning of the glass in the guides, correct pressure against the seals, and the absence of stresses that could shorten the component's service life.

How to effectively collect used body components
