Purpose and vehicle placement

The presented seal is designed for installation on the rear axle of the vehicle, on the left or right side. This placement allows for the restoration of the continuity of the factory seal in the rear passenger door area, which is important both for protecting the interior from moisture and for the acoustic stability of the cabin. The component has been designed for the Avant body style, taking into account the characteristic geometry of the door opening.

Function and benefits of installation

The inner door seal performs several key operational functions:

• limits the penetration of water and moisture into the vehicle interior in the area of the sills and upholstery,
• reduces wind noise and tire noise, improving acoustic comfort,
• stabilizes door closure, affecting the operation of the lock and hinges,
• supports maintaining the proper temperature in the cabin through better insulation.

Thanks to the use of an original solution for the Audi brand, the proper guidance of the door edge and correct adhesion to the bodywork are maintained, which translates into predictable body behavior in daily use.

Product characteristics and fitment

The seal has been developed as a component dedicated to a specific generation of the A6 model in the Avant version, which means that its profile, length, and geometry are adapted to the factory mounting points. Such a solution minimizes the risk of leaks typical of universal replacements and facilitates installation without the need for modifications. The product belongs to the Door seals group, which guarantees structural consistency with other sealing elements in the vehicle.

Condition and service application

The item is offered in used condition, which allows for an economical repair while maintaining the manufacturer's original specifications. This type of solution is particularly beneficial for comprehensive body and paint work, door replacement after a collision, or when removing the effects of long-term use, such as wear or rubber deformation. A properly selected seal helps restore the correct fit of the door panel to the body and reduces the need for additional adjustments.
