I have to inform you that Audi didn't fit Bowden cables in my electric mirrors, but the windows work great!

there it is-



Electric mirror control module. Water damage. It's a great mounting location; behind the glovebox, on top of the air duct up against the bulkhead, and right below the fresh air flap into the the scuttle area. And right beside the servotronic module
There's a fair bit to dismantle to get to it. Some of which is good to do when replacing the aircon fan
