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.
I'm having issues finding my ignition wire, my car looking different then the diaphragm
