Purpose and fitment

The presented rear left window is designed specifically for the 3 Series E91 Touring body, taking into account the geometry of the window frame, roofline, and the characteristic side profile of the BMW. Its placement in the rear zone on the driver's side ensures proper illumination of the luggage compartment and rear seats, while maintaining the factory structural rigidity of the body.

Thanks to the use of the original BMW design, the component maintains the correct bending radii, angle of inclination, and method of seating in seals and trims, which facilitates installation and reduces the risk of leaks after replacement.

Glass and finish characteristics

The glass belongs to the group marked as AS3, which in practice means a special type of glass used in selected body zones, with different parameters than standard windshields. This solution allows for better adaptation to the structural requirements of the rear part of the estate body and the specifics of the trunk construction.

The black finish in the Glanzschwarz variant ensures consistency with factory BMW trims and window frames, creating a uniform, aesthetic side line. This color choice also facilitates integration with original body trim elements without the need for additional modifications.

Condition, origin, and application

The component comes from the BMW line and is part of the Other car windows and window parts group, meaning it was designed as an integral component of the vehicle's factory glazing system. The used nature of the product makes it a cost-effective solution for post-accident repairs, replacing a damaged window, or restoring the car to its original specification.

In practice, the window will work well both for local repair of a single element and for broader bodywork and paint jobs in the rear part of the body, where maintaining the original lines and proportions of the BMW 3 Series E91 Touring is required.

Benefits of using original BMW glass

• Factory fitment for the E91 Touring body – consistency of shape and installation method with the vehicle's construction.
• Consistent Glanzschwarz finish – aesthetic connection with other elements of the side window line.
• Appropriate AS3 glass type – adapted to the requirements of the rear body zone.
• Possibility of use in post-accident repairs and vehicle restoration.

Using an original side window allows for maintaining the structural rigidity designed by the manufacturer, proper seal adhesion, and correct water drainage from the window frame area, which is important for body durability and user comfort.
