Purpose and function of the seal

The presented seal is dedicated for installation in the rear part of the body on the left side, in the area of the door window guide. Its task is to limit the penetration of water, dust, and noise into the cabin, as well as to stabilize the window edge during the operation of the lifting and lowering mechanism. The design, matched to the Audi door profile, allows for maintaining the factory adhesion geometry, which is crucial for proper closing and lock operation.

Construction and technical properties

The seal is made of flexible rubber material, which ensures adequate elasticity in contact with the window and the door frame. The working profile has been designed to:

• maintain even pressure along the entire length of the window edge,
• compensate for minor body deformations while driving,
• reduce vibrations and rattling resulting from door operation.

Such a solution promotes maintaining a stable position of the window in the guide and reduces the risk of leaks at critical contact points.

Benefits of using an original Audi seal

Using a component sourced from Audi allows for maintaining the structural consistency of the entire door system. The most important advantages include:

• Factory fit to the body – no need for modifications, proper adhesion to the frame and window.
• Stable operation of the window mechanism – reduction of movement resistance and the risk of jams resulting from an improper seal profile.
• Better acoustic insulation – reduction of wind noise in the rear part of the cabin at higher speeds.
• Interior protection – reducing the risk of moisture ingress near upholstery and metal elements.

As an element from the Window seals and moldings group, this part supports maintaining the proper rigidity and tightness of the entire door perimeter, which is important for both comfort and body durability.

Condition of the element and service application

The seal comes from disassembly and is intended for reinstallation in a vehicle where it is necessary to replace a worn or damaged window seal. It is particularly useful in situations where symptoms occur such as:

• increased noise in the rear part of the cabin with windows closed,
• traces of moisture near the door edge,
• loose fit of the window to the frame or noticeable vibrations while driving.

Using an original element allows for restoring proper window operating conditions and limiting further wear of lifting mechanisms and guides.

Why it is worth choosing used OEM elements

In the case of body elements and seals, using parts from the first assembly often ensures a better fit than random replacements.
