Purpose and function of the mechanism

The presented lock mechanism is the component responsible for locking and unlocking the front left door in Audi vehicles, integrated with the central locking system. This assembly combines the mechanical part (latch, gears) and the actuator component, which works in conjunction with the vehicle's electrical installation.

Its placement in the front – left side of the body makes it a key element for driver or passenger comfort, depending on the body version and market. A properly functioning lock ensures secure door closing, correct latching while driving, and stable cooperation with the vehicle's safety system.

Construction and technical parameters

The mechanism belongs to the Locks and latches technical group, meaning it is responsible for physically keeping the door in the closed position and transmitting signals to the body control modules. The assembly includes an integrated actuator, a gear system, and components that interface with the exterior and interior door handles.

The product's technical data also includes the wheel rim width parameter assigned to the vehicle from which the part originated. This information is important for identifying the donor vehicle and confirms the component's compatibility with the specific factory configuration of the car.

Condition, origin, and fitment

The offered door lock comes from the original Audi production line, which translates into a precise fit with the door sheet metal, guides, and other structural elements. As a used part, it retains the factory mounting geometry, ensuring that installation is straightforward and does not require any modifications.

Selecting the correct lock for a specific vehicle should always be based on comparing the part number and the placement on the vehicle. If necessary, it is worth comparing the shape of the housing, the type of electrical connector, and the mounting layout with the element currently installed in the car.
