How to remove and install the door lock and door lock cylinder from a door on Audi A4?

To remove the latch, start by taking off the door trim panel and watershield, then remove the window glass regulator from the door. Disconnect the electrical harness connector at the door lock, followed by disconnecting the operating rod from the door handle and unclipping it from the lock assembly, noting the rod's location. Next, remove the two fasteners and withdraw the lock unit along with its base plate from the door, then disconnect the operating cable housing from the lock unit. Unhook the interior handle operation cable from the lock unit by rotating the cable end 90 degrees and unclipping it. For installation, reverse the removal steps. To access the lock cylinder, open the driver's door and remove the lock cylinder cover cap, then turn the Torx bolt counterclockwise until it stops to release the lock cylinder. Remove the lock cylinder from the outside door handle, and for installation, reverse the removal steps. For the outside handle, fully close the window and remove the door trim panel and watershield, then take out the window glass regulator. Disconnect the operating rod from the lower clip, rotate it, and remove it from the outside handle clip. Rotate the locking element to release it from the rear of the handle and lock cylinder, then insert a screwdriver through the door plate into the release slider and slide it towards the latch end. Remove the handle and trim from the outer surface of the door, and if necessary, detach the door handle trim using a small flat-bladed screwdriver by pushing the release tab. For installation, reverse the removal steps.
