Does anyone have a schematic or up to date wiring diagram for a 2019 Express S4 EFI? My gas gauge doesn't work and I can't find any wiring diagrams that are close to this model year, not alone with EFI.

Check the wires at the gas tank there should be 2 one female space connector on the side and another directly in the center of the sending unit sometimes those wires go bad, break or fall off. Also the fuel gauge doesn't work unless you are depressing the pedal :twocents:
