Dr Rotech
I have just purchased a Dr Rotech diagnostic tool. I plugged it into my 912 uls and on circuit A it came up with a fault in ignition sw.. on circuit B it passed all.
Engine runs fine so it has me a bit stumped on why it failed on A...
Can any one out there in internet land tell me what the problem would be and where to look. It only happen on the A module plugs.
