Vehicle Application and Placement

The presented actuator is designed for installation in the rear left door area, allowing for precise integration with the factory lock mechanism. This ensures compatibility with the original electrical system and door construction, eliminating the need for modifications to wiring harnesses or mounting points.

The component works with the factory locking system, responsible for:

• mechanically moving the bolt in the rear driver's side door,
• correctly responding to signals from the central locking system,
• stably maintaining the closed or open position of the door leaf.

Technical and Functional Characteristics

The door lock actuator operates as an executive element within the door system, converting control signals into bolt movement. The design intended for Audi ensures appropriate locking force and consistent operation under typical usage conditions.

Key features of this component include:

• dedicated placement in the rear left part of the vehicle body,
• compatibility with the factory door lock mechanism,
• retention of original mounting geometry and connection points.

This allows for an organized installation process, and the actuator, once installed, works seamlessly with other components of the locking system without requiring additional adjustments.

Component Condition and Practical Application

The offered actuator is a used part, meaning it comes from a dismantled vehicle and has been verified for its suitability for further use. This type of component is particularly beneficial when a damaged mechanism needs replacement while keeping repair costs reasonable.

Choosing an original, dismantled actuator allows for:

• maintaining consistency with the factory Audi locking system,
• reducing the risk of fitment issues common with aftermarket parts,
• preserving the correct operation of the central locking system in the rear left door area.

Benefits of Using an Original Audi Actuator

Using a factory actuator in the Audi A4 Avant translates to stable operation of the locking system and predictable door behavior during daily use. The original design ensures proper alignment with the door panel, guides, and other mechanism components.

Key advantages include:

• maintaining factory lock operating parameters,
• no need for electrical system modifications,
• consistency with other locking system components in the vehicle.

This solution is particularly important for vehicles where maintaining the original equipment configuration and predictable central locking performance in the long term is crucial.
