Purpose and vehicle placement

The presented inner seal operates in the rear zone of the body, where it is responsible for the proper sealing of the door edge. It can be used on both the left and right sides, which facilitates the selection of the component during post-accident repairs or when replacing worn-out parts. This solution allows for maintaining the structural and visual consistency of the entire rear part of the body.

Technical and functional characteristics

The seal has been designed as a component that works with the factory Audi door frame, ensuring:

• stable adhesion to the door edge and bodywork,
• reduction of noise penetration from the outside into the passenger cabin,
• increased protection against water, dust, and fine contaminants,
• maintenance of the correct door closing geometry in the rear part of the vehicle.

Thanks to the use of a properly selected material compound, the seal maintains flexibility and tightness within typical operating temperature ranges, which translates into predictable performance during daily vehicle use.

Benefits of using an original Audi seal

Choosing a component from the Audi brand allows you to maintain factory standards of fit and door operation. In practice, this means:

• no need for mounting modifications or trimming the profile,
• better compatibility with existing hardware and door upholstery,
• consistent appearance of the door edge relative to other seals in the vehicle,
• reduced risk of rattles, squeaks, and leaks after installation.

This solution is particularly beneficial for body repairs, where maintaining the original acoustic and functional characteristics of the vehicle is essential.

Component condition and service application

The seal is offered in a used condition, making it an attractive option for economical repair of the rear body section. It can be used both for replacing a single damaged section and for comprehensive renovation of the rear doors on the left or right side. A properly selected component allows for restoring correct door closure and limiting the ingress of water and noise into the interior.
