Purpose and vehicle placement

The presented lock is dedicated for installation in the rear right door area, which means its geometry, mounting points, and the way it interacts with rods and handles are specifically adapted to this part of the body. As a result, the component maintains the correct position relative to the pillar and seals, and the latch operation is repeatable and predictable.

The placement on the vehicle has been selected to:

• ensure proper locking and unlocking of the door,
• maintain the tightness and stability of the closure,
• preserve compatibility with Audi's factory design solutions.

Technical and functional characteristics

The lock belongs to the Locks and latches group, which means it is responsible for the mechanical securing of the door and interaction with the interior and exterior opening systems. The design intended for Audi models allows for:

• stable guidance of the lock tongue relative to the striker in the body,
• proper operation within typical operational load ranges,
• maintaining appropriate rigidity of the connection between the door and the body after closing.

As an original Audi component, the lock has been designed to maintain factory assembly clearances, which facilitates adjustment after installation and reduces the risk of rattles or unwanted noises while driving.

Component condition and service application

The offered lock is a used part, which in practice means it comes from disassembly but is still suitable for further use. This type of solution is beneficial for users looking for a compromise between repair costs and maintaining the vehicle's original design. In many cases, installing a used lock allows for restoring full door functionality without the need for interfering with the installation or modifying mounts.

The component will prove particularly useful in situations such as:

• problems with closing or locking the rear right door,
• mechanical damage to the lock after a collision or intensive use,
• the need to replace a worn mechanism while maintaining original design solutions.

Benefits of choosing an original Audi lock

Choosing an original lock for the Audi A3 8P / A4 B7 primarily means reliable fitment to the body and predictable behavior during daily use. The lack of need for modifications to mounts or rods shortens installation time and reduces the risk of subsequent adjustment problems. For workshops and users, this means a more predictable repair process.

If you are planning a comprehensive repair of the locking mechanisms in your Audi, it is worth considering other elements from this group – you can find them in the Locks and latches category, which will make it easier to select compatible parts in one place.
