Can you please tell me which fuse controls the Windscreen Washer Pump on an Audi 8V 2018 model? I can’t see it listed here nor in my car owner’s handbook.

I also note that you have both Fuse 15 and Fuse 20 in the engine bay marked as Farkop (which I assume is the Horn). My Audi handbook only shows that as Fuse 15 but doesn’t list Fuse 20.
