Can anyone tell me why i have a rapid clicking noise from my 2000MY UK impreza turbo, it has been remapped to suit mods but can't remember it doing it before ?!
I have located it to a little unit that is bolted to the back of the n/s inlet manifold just behind/below the coil pack , it has 2 vacuum hoses to it and a blue coloured plug connector ??
Can anyone tell me what this is and why it is clicking so fast ??

Thanks

sounds like an injector to me

I'm led to believe that a clicking injector is not necessarily bad, but I'm by no means an expert... Is it very loud or just noticeable?

catons scooby

sounds like the boost solenoid

Nope , definately not an injector and i thought the boost solenoid was on the o/s of the engine bay ??
Car is running and going well , just can hear the thingy clicking at idle !

Any other thoughts ???

Have you still got the test connectors connected?

Good question ?? where abouts would they be ??
By the bottom of the steering column aren't they ?

Plums!

Boost solenoid is on the front left strut (looking from the front of the car) just behind the airfilter box, if I rember rightly it's blue and black and marked denso, on the MY2000 should have 2 vacuum hoses connected to it.

Good luck,

Doing this from memory... and I sometimes get it wrong... pretty sure the test connectors are the green ones just under the dash by the steering column.

Plums!

Yep that's the ones, green to green. simple test to see if there connected is just to switch on the ignition lights (without starting the engine).... if things start to click, wurr, cooling fans come on intemitently and so on then it's connected.

BTW Is the thing clicking the idle control valve? I can't recall where that lives on a MY00 off hand... my STi 5 is in bits at the moment so I can't check!

Checked the connectors and definately disconnected , the noise is also definately not the boost solenoid or the idle valve .
If you have got a top mount on it would be quite hard to see , but as i have got a FMIC you can clearly see the small black unit bolted to the manifold just behind and below the ignition coil pack .
It has a blue coloured electrical plug one end and 2 vacuum hoses connecting to the bottom end which is a browny colour ?!

Any more ideas ??
thanks .
