The idea is to control the length of time the glow plug stays on after starting the engine. With the Di engine it is a bout 5 minutes. The aim of using the timer is to reduce this. Some people reduce it to about 30 sec after startup.
The best references to this are here:

The first link has a lot of detail as well as the usual added trivia.
My suspicion is that the glow plug issue with the Di engine is part of the grenade issue. Nissan seem to have reduced the after start timing of the plugs with the CRD engine.
Also with any of the glow plugs the indications being they need to be physically checked about 80,000 Km after installing.

Thanks for that outback, I'll put it on the to do list, thanks 3 dogs for the pm. Ok so I've got my gauge kit and am keen to put it in. So I have question, to get the dump pipe out do I need to undo it where it joins onto the turbo, bellow the heat shield? because I can't get that heat shield out no matter what I try.
-
Lol. You just gotta hold your tounge the right way bud. It will come out. This needs to be removed before you remove the dump pipe too.
-
What else has to be removed, I have got rubber heater hoses on the motor side off, the bracket holding the solid ones. The solenoid bracket above the turbo. I got it close once but the aircon pipes were gunna get chopped. So I slide back to where it started. Thanks for your help mudski

You shouldn't have to force it out, like mudski said just gotta get your tongue at the right angle :tongue: . When you get it out, chop the corners down with a grinder to give yourself a bit more room.

I also struggled for hours, I then went inside for a coffee break and to read up more on how it comes, went out for another go and presto it came out in with no trouble at all. You just have to jiggle it in the right way.

Ok so Ive been tring for hours yesterday and all morning today, my patience is done, after searching the forum some more I can tell I'm having the drama is because it's a ST-L with rear aircon. Which is why I can get it so close but the rear aircon pipes get in the way. I'm gunna get the clamp set up for the egt which I reckon I'll be able to fit on without completely removing the shield. Efin thing, and sorry if I insulted any of my Japanese neighbors.
-
Ahh rear air con too. Of course. I did read somewhere a guy attacked his with a dremel so it was easier to move around those pipes.
-
Yeah the bloody rear aircon.lol I wish I had a dremal, I thought about pulling out the 6" grinder but was running out of time. I'll put it down to a practice run. Lol. Think I'll do the boost gauge first

A Dremel is a must in my opinion. Not expensive and such a handy tool to have.
