Purpose and vehicle placement

The presented lock is dedicated to the rear right side of the body, making it a perfect fit for the factory door layout of the Audi A4 B8 generation. Its placement in the rear seat area requires maintaining the correct geometry of the mechanism so that the door closes smoothly and the locking action is repeatable and stable.

The component has been designed to work with factory guides, hinges, and seals, which reduces the risk of stress and leaks within the door area. This ensures proper interior acoustics and an appropriate level of passive safety.

Construction and technical function

The lock is responsible for several key functions in the rear doors:

• mechanical locking of the door leaf against the body pillar,
• stable maintenance of the closed position while driving,
• cooperation with internal and external door handle linkages,
• integration with the central locking system and cabin controls.

The factory design ensures the correct positioning of mounting points, which facilitates installation and allows for maintaining the original door handle operation line. Precise fitment with the door panel reduces play, squeaking, and unwanted vibrations that may occur when using components of uncertain origin.

Benefits of using an original lock

Choosing a door lock dedicated to Audi allows you to maintain the consistency of the entire locking system. In practice, this means:

• maintaining the factory characteristics of the door handle and locking mechanism operation,
• proper cooperation with the vehicle's electronics,
• reduced risk of problems with closing or locking the door,
• easier diagnostics in case of any future malfunctions.

Original origin from the Audi group promotes long-term, repeatable operation of the mechanism, which is particularly important in heavily used fleet cars or vehicles used daily in city traffic.

Condition and service application

The item is offered as a used part, which is a cost-effective solution while maintaining compliance with factory specifications. This type of component works great in:

• post-accident repairs of the right rear body side,
• troubleshooting locking or opening issues with the rear doors,
• servicing vehicles where the lock mechanism has worn out or been damaged.

Replacing it with an original lock from the same design group allows for reduced installation time and avoids installation modifications, which is important for both workshops and individual users.
