Audi Q2 GA Door Lock Rear Left N/S Door Latch Catch Actuator 4G0839015J

The Audi Q2 GA Rear Left Door Lock Actuator is a precise component from the Locks and Latches group, designed to control the locking mechanism of the rear left door. It is responsible for secure closing, unlocking, and cooperation with the central locking system and body electronics, which directly impacts the comfort and safety of using the car. Thanks to its factory-designed construction for the Audi Q2 GA, the actuator ensures proper fit for door installation and correct interaction with other components.

Vehicle Purpose and Location

The actuator is designed for installation in the rear left door area, specifically in the zone responsible for locking and unlocking the door leaf. Its placement on the vehicle, designated as rear – left side, means the element works with the door lock, linkages, and the electrical harness assigned to this part of the body. Correct fitting to the specific position in the car minimizes the risk of leaks, mechanical play, and central locking system errors.

Function and Vehicle System Integration

The actuator is responsible for converting an electrical signal from the comfort module or central locking control unit into mechanical movement of the latch. In practice, this means:

• controlling the locking and unlocking of the rear left door via remote control or an interior button,
• cooperating with the auto-locking function while driving, if the vehicle is equipped with it,
• maintaining synchronized operation with other actuators in the doors, trunk lid, and fuel filler flap.

Thanks to its construction, which aligns with solutions used by Audi, the component maintains proper operating parameters, reducing the risk of improper closing, accidental opening, or errors indicated on the instrument cluster.

Product Characteristics and Fitment

The actuator is part of the original components used in Audi vehicles, which translates to compatibility with factory mounting points, housing shape, and electrical connector. For the user, this means:

• installation without the need for mechanical modifications to the door,
• maintaining the factory geometry of the lock linkages and levers,
• compatibility with the vehicle's electrical system parameters.

The product is offered as a used genuine part, allowing for an economical repair of the locking system while preserving the design intended by the vehicle manufacturer.

Condition, Verification, and Service Application

The actuator is classified as 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 useful in situations where:

• the original actuator in the Audi Q2 GA has stopped responding to signals from the remote or button,
• there are problems with intermittent locking or the inability to open the rear left door,
• the element needs replacement with a part that has factory-compliant parameters.

Using an original actuator from the same construction group helps reduce the risk of incompatibility that can occur when using aftermarket replacements with different specifications.
