Replacing a Failing Door Lock & Latch on a 2008 Audi S6, works for A6 & RS6 C6 4F

Join me in the latest of the Audi Chronicles as I replace a failed door lock/latch assembly without removing the window frame. The service manual says this is required, but it can be done without complete removal.
The door stopped unlocking and locking so it had to be manually opened from inside. There is a small cover that had to be removed from the door jamb to manually lock the door with the key while this was broken.
