Purpose and function of the lock

Door Lock Audi A4 B8 Front Right O/S Latch Catch Actuator is a complete locking and actuator unit designed for installation in the front right door. It is responsible for:

• mechanical locking and unlocking of the door on the driver or passenger side, depending on the body version,
• cooperation with the central locking system and remote control operation,
• proper operation of the external and internal door handles,
• transmitting signals to the vehicle's electrical system (e.g., door open status).

Thanks to its precise fit for the specific mounting location, the lock ensures correct geometry of the cables and mechanisms, which translates into stable and consistent door operation.

Construction and vehicle fitment

The component has been designed as part of the Audi door system, taking into account the specific construction of the front right side of the body. This means:

• compatible mounting points in the door shell,
• cable and lever routing designed for the specific model,
• electrical connector adapted to the wiring harness in the Audi A4 B8.

Such a fit allows for maintaining factory-standard component alignment and reduces the risk of play, rattles, or improper door closing after installation.

Benefits of using an original Audi lock

Choosing an original door lock for an Audi offers a number of practical advantages:

• maintaining compatibility with the central locking system and vehicle electronics,
• no need for modifications to the installation or mounting points,
• consistency with factory comfort and safety settings,
• reduced risk of diagnostic errors and module communication issues.

As a result, the installation and configuration time is shorter, and the risk of operational problems is lower compared to aftermarket replacements of uncertain origin.

Condition, verification, and practical application

The offered lock is a used part, which in practice provides a favorable compromise between cost and maintaining original Audi quality. Before being offered for sale, this type of component is standardly verified for:

• proper operation of the locking mechanism,
• efficiency of the electric drive (actuator),
• condition of connectors and housing for mechanical damage.

A component prepared in this way will work well both for standard repairs after a lock failure and for replacing a worn-out part, restoring proper operation of the front right door.

How to choose the right lock for your Audi

To select the appropriate door lock, it is worth paying attention to:

• the exact model and generation of the vehicle (A4 B8),
• placement on the vehicle – in this case, front, right side,
• compatibility with the existing electrical installation and central locking system.
