Does anyone have (or know where I can get) the circuit diagrams for the M3W (2013) version? I have the wiring loom diagram but I need the detailed one(s) which show what goes where. My horn doesn't work but the fuse is OK. The flasher unit doesn't work, the Hazards and indicators just stay on or off. I am competent at fixing electical/electronic circuitry, I just need the layout schematics.
