Purpose and Function of the Door Lock

The presented component belongs to the Locks and Latches group and is responsible for the secure, controlled locking of the left front door in a Volkswagen Golf. The integrated actuator works with the vehicle's electrical system, allowing control via remote, key cylinder, or interior buttons, depending on the car's configuration.

The vehicle placement has been factory-optimized for door and guide geometry, which translates to:

• stable positioning of the mechanism inside the door panel,
• proper interaction with the exterior and interior door handles,
• consistency with factory central locking settings.

Construction and Technical Specifications

The left front door lock for the Volkswagen Golf is designed as a compact element, combining mechanical parts with an electric drive. The locking mechanism works with rods and handles, and the built-in actuator is responsible for automatic door locking and unlocking.

The component has been prepared for use in the factory door system, considering the correct vehicle placement and compatibility with original mounting points. This ensures a systematic installation process without the need for structural modifications.

Condition, Fitment, and Application

The offered lock is a used part, which means it retains the original manufacturer's specifications while offering an attractive price compared to new components. For correct selection, it is recommended to compare your door configuration and electrical system with your vehicle's existing setup.

This part is particularly useful in situations where the vehicle exhibits symptoms such as:

• no response from the left front door to central locking commands,
• problems with closing or maintaining the locked position,
• irregular operation of the passenger side door actuator in RHD versions.

Benefits of Using an Original Lock

Using the original left front door lock in a Volkswagen Golf ensures consistency with the factory body and electrical system construction. Proper door fitment reduces the risk of play, leaks, and central locking calibration issues.

Choosing an original part from the Locks and Latches group also means:

• maintaining the mechanism's operating characteristics as intended by the manufacturer,
• compatibility with factory wiring harnesses and connectors,
• consistent operation with other locks in the vehicle.
