Purpose and function of the lock

The presented mechanism is dedicated to the rear right door in Audi models, where it is responsible for mechanical locking and unlocking in conjunction with the handle, lock cylinder, and central locking system. Its design is adapted to factory mounting points, ensuring full sealing and proper door closing geometry after installation.

The location on the vehicle (rear – right side) is significant both in terms of the housing shape and the operation of the linkages and connectors, which is why the part should be used exactly in the position for which it was designed.

Construction and technical compatibility

The door lock uses an internal latch mechanism that works with linkages and the central locking actuator. The housing is prepared for installation in the factory door opening, and the electrical connector allows for integration with the vehicle's wiring without the need for harness modifications.

Thanks to the use of the original Audi design, the following are maintained:

• proper cooperation with the factory central locking and comfort electronics,
• appropriate door closing force,
• stable positioning of the door relative to the body.

Benefits of using an original lock

Choosing an original lock mechanism for the Audi A4 B8 / Q5 8R allows you to avoid problems typical of replacements, such as inaccurate fitment or unstable latch operation. The factory geometry of the component translates into quiet door operation, proper closing, and correct functioning of the locking feature via the remote or the button inside the cabin.

A used part from dismantling is a cost-effective solution that also allows you to maintain the original build quality characteristic of the Audi brand. This is particularly important for components responsible for safety and daily comfort of use.

Condition, installation, and service application

The part comes from dismantling, which in practice means it has been used in a vehicle but is still suitable for further use. The mechanism is suitable both as a replacement for a lock damaged in a collision and for typical operational faults, such as locking problems, door not closing, or lack of response to the central locking signal.

Installation is carried out at factory mounting points, using original screws and clips. With properly performed service, the lock should work with the existing electrical system after installation without the need for additional programming.
