Purpose and vehicle placement

The presented seal is a component intended for the rear part of the body, with the possibility of installation on both the left and right sides. This solution facilitates selection and assembly, especially when servicing both rear doors simultaneously. Thanks to its precise fit for the Audi S8 V10 construction, the seal works in harmony with the door line and body frame, ensuring stable seating and proper pressure along the entire perimeter.

Technical and functional characteristics

The rear door seal is responsible for maintaining proper sealing between the door and the body, which directly impacts:

• limiting the ingress of water and moisture into the cabin,
• reducing wind noise at higher speeds,
• dampening minor vibrations and rattles coming from the door area,
• stable guidance of the door edge during closing.

The appropriately selected cross-section and material flexibility allow for maintaining proper pressure against the door panels and body frame, which translates into vehicle comfort during daily use.

Benefits of using an original Audi seal

Using an original component from the Doors and door panels group ensures a proper fit to the Audi S8 V10 body geometry, without the need for modifications or fitting aftermarket replacements. This is particularly important for models with a higher standard of soundproofing, where the quality of the seal affects the overall driving experience.

The main advantages of this solution include:

• compatibility with the factory door and pillar construction,
• consistent appearance of the door edges when closed,
• maintenance of the appropriate level of acoustic insulation,
• the ability to use the same type of seal on both sides of the vehicle at the rear.

Condition of the item and service application

The seal is a removed part, which allows for an economical repair of the door zone while maintaining the manufacturer's original specifications. This type of component is particularly useful in situations where the existing seal has suffered from operational wear, has been mechanically damaged, or deformed due to improper installation. Replacing it with an original seal allows for restoring proper door closing and reducing unwanted noises coming from the rear body area.
