Purpose and function of the door stopper

The presented stopper is designed for installation on the rear axle of the body, on the left or right side, allowing for flexible application depending on service needs. Its task is to mechanically limit the door opening angle, keep them in stable intermediate positions, and protect the bodywork from collision with adjacent elements. A properly functioning stopper reduces the load transferred to the hinges and mounting plates, which translates into a longer service life for the entire door assembly.

Compatibility with the Audi C7 platform

The stopper has been designed specifically for the body structure of the C7 generation Audi A6, S6, and RS6, maintaining the mounting geometry and operating characteristics specified by the manufacturer. This means that after proper installation, the component works with factory hinges and locks without the need for modifications or adaptations. Original Audi branding helps maintain technical consistency with other door components, which is important for both safety and user comfort.

Installation and operational characteristics

The stopper is intended for installation in the rear part of the vehicle, on the right or left side, which facilitates service logistics and part selection during post-accident or maintenance repairs. The OEM design allows for installation in place of the factory component, using existing mounting points in the door and body pillar. As a result, the replacement process is predictable, and after correctly tightening the mounts, you achieve repeatable, smooth door operation without unwanted play or jamming.

Application in service practice

This type of stopper is particularly useful in situations where the doors no longer maintain stable positions, sag when opening, or where the door is uncontrollably "pulled" open in strong winds. Replacing a worn component with an original Audi part allows you to restore the factory feel when opening and closing the doors and reduce the risk of paint and sheet metal damage. N/O/S (New Old Stock) condition means the part is a genuine original component, which for many users is a beneficial compromise between cost and maintaining the original manufacturer's specifications.
