Purpose and body fitment

The presented window has been designed specifically for installation in the rear left door of the first-generation Volkswagen Touran. Its placement in the rear side zone ensures proper cooperation with the window regulator mechanism, door seals, and door frame, which translates into stable glass guidance and a reduction in unwanted vibrations while driving.

The AS3 glass class indicates an increased level of tint compared to front windows, which improves the comfort of rear-seat passengers, reduces interior heating, and limits glare. Thanks to the preservation of the factory shape and thickness, the window works with original guides and moldings without the need for any door structure modifications.

Technical parameters of AS3 glass

Glass marked with the AS3 class is characterized by an increased degree of tint while maintaining the required safety standards for rear side windows. This type of window:

• provides limited light transmission, improving protection against solar radiation,
• supports the maintenance of a stable temperature inside the cabin,
• increases the privacy of passengers in the rear seat,
• is adapted to work with standard seals and window lifting mechanisms.

By maintaining the manufacturer's original specifications, the window retains the appropriate rigidity and resistance to stresses generated during door closing and driving on uneven surfaces.

Condition of the component and benefits of using a used part

The offered window is a used component, which allows for a significant reduction in repair costs while maintaining the original build quality characteristic of the Volkswagen brand. Unlike many aftermarket replacements, original glass from dismantling retains factory fitment parameters to the door frame, which facilitates installation and minimizes the risk of leaks.

The use of a used side window is particularly beneficial in the case of post-accident repairs, replacement after glass breakage, or body restoration, where the priority is to combine technical correctness with the control of service costs.

Installation and service aspects

The rear left window for the Volkswagen Touran has been prepared for installation in the factory location, using standard mounting points and guides. With properly performed installation, it is possible to:

• achieve smooth operation of the window lifting mechanism,
• maintain tightness at the contact point between the glass and door seals,
• restore the original side line of the body.

During installation, it is recommended to check the condition of the guides, seals, and the window lifting mechanism to fully utilize the potential of the newly installed component and avoid the need for further intervention in the near future.

Selection by OEM number and technical support

Due to differences between body versions and production years, the selection of the appropriate side window should be based on the OEM number and vehicle data. To minimize the risk of error, it is worth using practical tips regarding part verification by catalog number and VIN – a detailed step-by-step description can be found in the article Guide: how to select the right car part by VIN and OEM number.
