16v idle with lights turned on - SOLVED

[clipperjay]

Isolate the headlights pull the fuses and check if the ISV is still getting current? If not, then you found the problem. Then I recomend you trace the whole loom for the headlights to see if any wires seem amiss or melted itself on the loom for the ISV failing that try and re run the three wires from ISV and controller to a seperate plug to the fuse box? Guess the wires to ISV are less to deal with than headlight wires!

Ant,

If you need a good MK2 Mechanic in the Sheffield area then you will not go wrong with my M8

He drives a Valver and what he don't know about VW's, ain't worth knowing...

I want to try and get to the bottom of this myself as I know how expensive electrics can be.

However if he knows how to diagnose issues with, and set up a k-jet properly, then I'll be getting in touch

Another update on this - I've finally solved it!

The problem was that someone had connected the spare spade terminal (green wire) on the ISV controller loom to a spare plug coming out of the fusebox.

The spare plug (grey/blue wire) came out of the 'D' plug on the fusebox, and shared a pin with the cigarette lighter illumination.

I've disconnected the wire now and all is well!
