Purpose and vehicle placement

The presented bracket belongs to the Brackets, mounts, and assembly parts category and is designed for installation on the rear right side of the vehicle body. It is responsible for the proper support and positioning of the bumper relative to the body structure, which is important for both aesthetics and the correct operation of adjacent components, such as wheel arches or covers.

Its placement in the rear passenger-side zone makes this component particularly important for repairs after corner collisions, bumper replacement, or restoring factory gaps between the bumper, fender, and trunk lid.

Technical and functional characteristics

As an original Audi component, the bracket is designed to maintain the factory rigidity of the bumper-to-body connection. Properly shaped mounting points and bumper guides allow for:

• maintaining a stable bumper position while driving,
• reducing stress on the paneling during minor deformations,
• easier removal and reinstallation of the bumper during service work.

This solution supports the maintenance of the correct geometry of the rear body section, which is not only visually significant but also practical – it facilitates the proper closing of the trunk lid and the installation of other protective elements.

Condition of the component and use in repairs

The bracket comes from disassembly, making it an attractive cost-effective alternative to new parts while maintaining the original manufacturer’s specifications. This type of component is particularly useful for:

• post-accident repairs of the rear body corner,
• replacing a damaged or deformed bumper mount,
• correcting bumper alignment after previous, imprecise repairs.

Using an original bracket from the same model generation reduces the need for adjustments and modifications, which translates into shorter working time and a more predictable final result.

Integration with other Audi assembly components

The bracket works with other rear bumper mounts and supports in the Audi A4 B9, creating a cohesive support system for the paneling. Replacing a damaged element with an original component from disassembly helps restore factory body line alignment and improve the overall rigidity of connections in the rear of the vehicle.

If you are planning a comprehensive repair or upgrade of the rear bumper mounting zone in your Audi and need other elements from the same group, such as additional brackets, supports, or guides, check the available parts in the Audi Brackets, mounts, and assembly parts category.

Technical support and knowledge about dismantled parts

When selecting used body components, it is worth using proven sources and knowledge about the use of parts from disassembly.
