Purpose and fitment for Audi A4 B9 8W

The presented window is dedicated to the rear right door of the Audi A4 B9 generation (8W designation). The design has been developed for factory mounting points, ensuring correct guidance in the tracks, airtight sealing against the weatherstrips, and compatibility with the stock window regulator mechanism.

Proper alignment of the window geometry with the bodywork translates into reduced wind noise, correct operation of the door locks, and maintenance of the proper rigidity of the side passenger zone.

Technical specifications of the rear right door window

As an element of the Car windows category, the rear right window for the Audi A4 B9 8W is manufactured using technology corresponding to the AS2 standard, which in practice means the use of glass with appropriately selected light transmission and mechanical strength. This type of glass is designed with user safety in mind and complies with homologation requirements for side windows.

The placement in the rear right part of the vehicle requires maintaining the correct edge profile, which enables proper interaction with seals, trim strips, and the door frame. Thanks to this, the aesthetic side line of the body and the correct operation of the door opening and closing system are maintained after installation.

Benefits of using original Audi glass

Using the original rear right door window in an Audi A4 B9 8W allows you to maintain the vehicle's factory parameters in terms of:

• lateral door structure rigidity,
• interior acoustics (reduction of noise while driving),
• correct operation of the window lifting and lowering mechanism,
• visual consistency with other windows in the vehicle.

For the user, this means stable seating of the glass in the frame, predictable behavior during operation, and preservation of the vehicle's utility value after side body repairs.

Condition of the part and use in accident repairs

The offered window comes from the segment of used original parts, which allows for economical vehicle repair while maintaining compliance with factory specifications. This is particularly important for accident repairs, replacing a damaged window after breakage or cracking, as well as for the reconstruction of the side body zone after a collision.

Selecting a window with the correct profile and manufacturing standard minimizes the risk of problems with door adjustment, leaks, or excessive vibrations while driving, which translates into comfort in daily use.
