Purpose and function of the component

The described moulding belongs to the Window seals and trim strips group and is dedicated to the rear, left area of the body. Its task is to guide and seal the door window, as well as protect the edges of the sheet metal and glass from mechanical damage and the influence of weather conditions. A properly selected moulding limits the ingress of water, dust, and noise into the cabin, which translates into stable vehicle comfort.

The component is mounted in the rear part of the body on the left side, which is important when selecting parts for a specific body version and door configuration. Precise adjustment to the door geometry allows for maintaining the line of factory gaps and proper adhesion of the window throughout its entire range of operation.

Original Audi origin

The moulding was designed by the Audi brand as part of the side window sealing system in the A5 8T generation model. This means maintaining the manufacturer's standards regarding geometry, rigidity, and compatibility with factory mounts. The original origin facilitates trouble-free installation and minimizes the risk of improper window pressure against the seals.

Compared to replacements, using an Audi component allows for maintaining the structural consistency of the body, which is essential for long-term operation, frequent opening and closing of the door, and the operation of the window lifting mechanism.

Performance and installation characteristics

The moulding is intended for installation in the rear, left part of the vehicle, which facilitates unambiguous selection relative to the specific installation location. The design provided by the manufacturer allows for installation in the factory location, using the original mounting points in the door. Thanks to this, it is possible to maintain proper window guidance and even pressure along the entire length of the edge.

As an element from the seals and trim strips group, the product contributes to:

• limiting the ingress of water and contaminants into the door interior,
• reducing wind noise in the rear part of the body,
• protecting the window edge and paint from abrasions,
• maintaining stable operation of the window lifting mechanism.

Condition and service application

The component is offered in used condition, which allows for an economical replacement of a damaged or worn moulding while maintaining the original manufacturer's specification. This type of part will work especially well for post-accident repairs, replacement after door edge corrosion, or in case of window leakage problems in the rear, left body zone.

Selecting the right moulding for a specific vehicle is facilitated by the manufacturer's markings and assignment to the appropriate mounting position. Thanks to this, it is possible to precisely recreate the factory configuration of seals in the Audi A5 8T.
