Can anyone help me interpret this engine error code I got on my 02 1.9tdi galaxy:

18074 Valve for pump-jet cylinder 1 (N240) Electrical malfunction P1666

I had a peek on another vag forum and someone was saying the problem was with their Injector wiring harness. Can anyone give me any clues as to where this is and how easy it is to replace?

Thanks,

Ian

18074/P1666 - Valve for Pump - Jet: Cylinder 1 (N240): Electrical Malfunction
18075/P1667 - Valve for Pump - Jet: Cylinder 2 (N241): Electrical Malfunction
18076/P1668 - Valve for Pump - Jet: Cylinder 3 (N242): Electrical Malfunction
18077/P1669 - Valve for Pump - Jet: Cylinder 4 (N245): Electrical Malfunction

18079/P1671 - Valve for Pump - Jet: Cylinder 6 (N245): Electrical Malfunction



the ecu reads the voltage to the jet, at the start of the injection period? fom what I gather? any extra resistance in this cabling system will bring up a fault code!
sounds like you have a U/S loom or a dodgy connector? a common problem! IIRC DaveG had this problem? do a search on the topic t has been covered before ;)

the-boss..... how the hell you thought it was a crank sensor code I'll never know? you a Ford techie? :lol:

the harness runs through the head to the injectors if you look at the engine on the right hand side of the head you will see a large black plug on the side of the head, unplug it and the bit it connects to on the head is the bit you need to replace, from memory you need to remove the inlet manifold to remove the rocker cover to unplug the harness from all 4 injectors inside the head, i think i payed about 50+vat for a harness, i think its quite a common fault? should only take about 2 hours max,
hope this helps
