Since I'm fairly convinced that I'm missing the hardware, you've just saved me the additional investigating. Time to uninstall the VCDS option.
I'm curious as to how you disabled the headlamp washers via VCDS. I got the same error code as you and don't have the system in my 2016 Lux although my 2013 CC had them. When I go to module 09 cent. elec and scroll thru the bytes there are no descriptions what so ever so I don't know what to uncheck. I would appreciate any help. Thanks.
