Door Lock Purpose and Function

The presented lock is dedicated for installation in the rear right part of the body, where it is responsible for the mechanical locking of the door and cooperation with the internal and external door handles. Its design was developed by the vehicle manufacturer, ensuring proper operating geometry, adequate closing force, and correct interaction with other door mechanism components.

Using an original lock in this location allows for maintaining the factory door operating parameters, reducing play, minimizing unwanted noises during driving, and ensuring predictable behavior during repeated opening and closing.

Benefits of Using an Original Volkswagen Part

Using a door lock from the Volkswagen offering translates into a range of practical operational benefits:

• factory fit to the door and body pillar structure,
• correct cooperation with the handle mechanism and linkages,
• maintenance of the manufacturer's designed locking characteristics,
• reduction of the risk of problems with closing or accidental opening of the door.

Thanks to this, the lock can be used both as a replacement part for repairing a damaged mechanism and during service work related to adjusting or refreshing the rear door area of the vehicle.

Technical Characteristics and Installation

The offered lock belongs to the Locks and Latches group, meaning it is the component responsible for physically securing the door wing to the body. Its placement in the rear right part of the vehicle requires maintaining the correct orientation during installation and proper connection with existing door system components.

Before installation, it is recommended to:

• verify the compatibility of the part with the specific body version and vehicle year,
• check the condition of the hinges and door adjustments to avoid excessive stress on the mechanism,
• check the operation of the handles and linkages after installation, including multiple test openings and closings of the door.

This type of procedure allows for stable, repeatable lock operation and reduces the need for later adjustments.

Part Condition and Service Application

The offered door lock is a used part, making it an attractive solution when cost optimization is a priority while maintaining the original design. This type of part is particularly suitable for everyday vehicles where functionality, compatibility with the factory system, and quick replacement of a damaged mechanism are important.

Replacement of the rear right lock is recommended, among other things, in cases of problems with closing, lack of secure locking, noticeable play in the mechanism, or incorrect cooperation with the internal or external handle.
