Hi I know when my injector wiring harness failed It seems to usually be cylinder 1. Its cheapest from VW dealer rather than Ford.

Well removed the injector loom, tested  all wires and connectors all 0 ohms resistance, checked all injectors 0 ohms, so got the trusty Wurth terminal cleared out clean all connectors refitted loom, engine flush an fresh oil an filter, done about 400 miles since an never missed a beat!

Hi, Glad it seems to be running fine, I hope it continues. The problem with these looms doesn't seem to be breaks in the wiring so they will always show continuity, but rather the spade connectors that connects to the injectors. For some reason they seem to open up and become loose on the injector spade. Although you can crimp them tighter, they seem to come loose again. If it happens again replace the loom.
