Purpose and function in the vehicle

The presented lock is dedicated to the rear body zone, where it is responsible for mechanical locking of the rear doors and cooperation with the lock control system. The mechanism combines a mechanical part and an electrical part (actuator), allowing for both manual and remote opening and closing of the doors via the central locking system.

A properly functioning rear door lock in the Sprinter W906 is crucial for:

• safe transport of cargo in the luggage or cargo space,
• maintaining the correct closing geometry of the rear doors,
• proper operation of the electrical system responsible for the closing signal.

Mechanism construction and system integration

The rear lock mechanism in the Sprinter W906 is based on a system of latches, levers, and springs that are responsible for stable locking of the door wings in the closed position. The integrated electric actuator transmits movement from the central locking control module to the mechanical part, which allows for convenient control from the cabin or via remote key fob.

This solution ensures:

• consistency of operation with the vehicle's factory security system,
• repeatable door closing without the need for excessive force,
• reduction of loads acting on hinges and door panels.

Benefits of using an original Mercedes component

Using an original rear lock in the Sprinter W906 allows you to maintain factory fitment with the doors and bodywork, without the need for modifications or adjusting mounting holes. The design is engineered for the specific model, which translates into:

• proper cooperation with the existing electrical wiring,
• compatibility with factory central locking settings,
• stable operation in typical operating conditions for commercial vehicles.

The component from the Doors and door panels group has a direct impact on the comfort of daily vehicle use – a functional lock eliminates the problem of doors not closing properly, accidental opening while driving, and false status messages about the closing state.

Condition, verification, and selection by part numbers

The offered rear door lock is a used part, which in practice means it comes from disassembly and has been verified for the correct operation of the mechanism and the actuator. This type of part is a cost-effective solution while maintaining the original build quality characteristic of the Mercedes brand.

Before purchasing, it is worth comparing the markings on your current lock with the data in the product technical specification and verifying the placement on the vehicle. This will ensure you select a component compatible with the configuration of your Sprinter W906 and avoid problems with installation or central locking operation.
