Purpose and function in the Audi A6 C5 Avant body

The window described is a fixed component, mounted in the rear left part of the estate body, which is significant for both the lateral rigidity of the chassis and passenger safety. It is responsible for providing proper illumination to the rear of the cabin while simultaneously reducing air turbulence and noise during driving. Thanks to its specific profile and fitment to the body frame, the continuity of the side line characteristic of the Audi A6 C5 Avant is maintained.

Performance parameters and installation benefits

The fixed rear left side window has been designed as a component dedicated to a specific model, which translates into:

• precise fitment with the window frame and seals,
• stable seating within the body structure,
• proper compatibility with other side windows and the rear part of the bodywork.

The fixed design of the window reduces the risk of leaks compared to moving parts, and the appropriate selection of AS2-type glass ensures proper light transmission and visibility comfort. Using an original window from the same model group allows for maintaining optical consistency with the vehicle's other glazing.

Characteristics of the used product

The item comes from a used vehicle, which in practice means that the window has already been in service under real road conditions. This type of component is a good choice for post-accident repairs, replacement after mechanical damage, or restoring a car to a near-factory state, especially in the case of older model years. A used fixed rear left side window allows for reduced service costs while maintaining the original geometry and character of the Audi body.
