Purpose and vehicle placement

The presented lock is designed for installation in the rear left section of the vehicle body, within the passenger door or rear seat area – depending on the body configuration. Placement in the side zone of the body requires a component with appropriately selected geometry, which is why using a dedicated lock allows for maintaining the correct operating line of the hinges, striker, and handle. Such a fit translates into:

• smooth opening and closing of the door without excessive resistance,
• stable retention of the door in the closed position while driving,
• reduction of unwanted play and rattling within the door panel area.

Construction and function of the door lock

The rear door lock in the Volkswagen Golf 5G acts as an intermediate element between the handle, the latching mechanism, and the door panel. It is responsible for mechanically locking the door panel against the body pillar and for transferring movement from the handle to the internal locking mechanism. Thanks to this, the door system remains sealed, and the body maintains proper rigidity during operation. A properly selected lock:

• ensures repeatable door closing with moderate force,
• reduces the risk of accidental opening while driving,
• works in harmony with factory solutions used in the given body model.

Benefits of using an original Volkswagen component

Using a lock dedicated to the Volkswagen Golf 5G from the Doors and door panels group allows for maintaining the structural integrity of the entire door module. The original component is designed for specific door geometry, which facilitates installation and minimizes the need for additional adjustments. This solution is particularly beneficial for post-accident repairs and when replacing worn-out service parts. The main advantages of such a solution include:

• factory fit to the door structure and body pillar,
• consistent cooperation with other elements of the opening mechanism,
• maintenance of predictable door behavior in daily use.

Condition and service application

The offered lock is a used item, making it an attractive alternative for service repairs where combining functionality with cost control is essential. Replacing the lock in the rear left section of the body is recommended in situations where problems arise with closing, latching, or keeping the door in the closed position. Using a component with the appropriate designation allows for restoring the proper operation of the entire door module without interfering with the body structure.
