As the title suggests I need the wiring diagram (current flow diagram) for the B5 AFN TDi motor, I have the A6 version but the wire colours seem different in places. (may not be, read down)
I found a stray plug, 2 pin purple, wires are brown/white and purple....ecu reports no IMTS (inlet manifold temp sensor) but that is present and is plugged in to a plug, identical to the loose one, but with wire colours red/white and white/red on that one. If I swap these, the ecu stops reporting no imts and instead says no egr valve! But that is already plugged in to another plug.
According to the A6 AFN wiring diagram:-
the G72 IMTS should be wired grey/red and brown.
N18 EGR plug should be red/white and white/red.....my current IMTS plug has those, maybe that plug should be on the egr solenoid, its a blue plug on that just now, need to check its colours of wire but its dark, the previous owner fitted the current engine and blew the S102 control fuse so none of the sensors have ever worked but now im thinking they have some plugs on wrong....
Anyone got the B5 AFN wiring pdf? Or know if the A6 one is actually the same anyway? If it is, most of the sensors are on the wrong plugs to the ecu LOL
