Purpose and vehicle placement

The presented lock is designed for installation in the rear right part of the body, in the passenger door. It is responsible for interacting with the handle, linkages, and control system, allowing the door to be opened and closed in a controlled manner, and remaining securely locked once engaged. Precise fitment to the Audi A4 B8 structure reduces the risk of play, leaks, or issues with the door closing properly.

Function and role in the locking system

The Door Lock Audi A4 B8 Rear Right O/S Latch Catch Actuator plays a key role in the side body security system. It is responsible for:

• mechanically keeping the door in the closed position while driving,
• proper locking using the central locking system or key,
• interacting with the internal and external door handle mechanism,
• stable guidance of the lock latch relative to the body pillar.

By maintaining factory geometry and mounting points, the lock allows for the restoration of proper door operation after a collision, wear and tear, or a previous unsuccessful repair.

Characteristics of the used component

The offered lock comes from an Audi vehicle and is a used component, which allows for combining an attractive repair cost with the preservation of the original design. This type of component is particularly useful when:

• the factory lock has suffered mechanical damage (e.g., after a door impact),
• there are problems with closing or keeping the door in the closed position,
• it is necessary to replace the lock with a part consistent with the factory Audi standard.

Choosing an original, used lock from the Locks and latches group allows you to maintain structural consistency and avoid typical problems associated with fitting aftermarket parts with different geometry.

Benefits of using an original Audi lock

Using a lock dedicated to the Audi A4 B8 for the rear right door translates into a number of practical benefits:

• Factory fitment – compatibility with original mounting points and door construction,
• Stable mechanism operation – proper locking and unlocking in daily use,
• Consistency with other system components – cooperation with handles, linkages, and the control system,
• Economical repair – the ability to restore full door functionality without the need to purchase a new subassembly.

For users who want to keep their car in good technical condition, this repair method is often the most rational solution, combining functionality with control over service costs.
