Purpose and vehicle placement

The seal has been designed specifically for the rear body section of the Audi Q2 GA, with the possibility of installation on both the left and right sides. This solution allows for flexible use of the component when replacing a single seal or during symmetrical restoration of both rear doors, which facilitates service work planning.

Technical and functional characteristics

As an interior component, the seal is responsible for maintaining proper tightness between the door structure and the vehicle interior. When installed correctly, it:

• limits moisture penetration into the door interior and cabin,
• stabilizes the door edge in the contact area with the body,
• helps reduce wind noise while driving,
• supports the maintenance of the factory door fitment geometry.

Thanks to a design consistent with the solutions used by the manufacturer, the seal works with factory mounting points and sheet metal profiles, which promotes secure seating and predictable behavior during operation.

Original origin and fitment for Audi

The product comes from the Audi line, which means maintaining the geometry, material hardness, and working profile consistent with factory design specifications. Original origin translates into:

• consistent fitment to the shape of the Audi Q2 GA door frame,
• compatibility with factory hardware and interior trim,
• easier installation compared to universal profile replacements.

As a result, replacing a worn seal with an original component allows for restoring the original tightness and acoustic comfort parameters without the need for body modifications.

Product condition and service application

The seal is a used component, which makes it an attractive solution for post-accident repairs, door service after bodywork, or gradual body restoration. In many cases, this allows for an economical restoration of proper door fitment when the original seal has been mechanically damaged or deformed.

Support with selection and expansion of work scope

In the case of work involving several elements within the door – such as hinge adjustment, lock replacement, or window position correction – using a properly selected seal helps achieve a final result consistent with factory specifications. If you are planning a comprehensive repair or upgrade of the door zone in your Audi and need other elements from the same group, such as inner edge seals, perimeter weatherstrips, or additional sealing profiles, check the available parts in the Audi door seals category.
