Idle control valve

As you know i have just finished my Mems3 conversion

Engine runs like a dream,, however with Igniton off the Idlec ontrol valve after its normal few clicks sits there with a very slight whistling noise.
It is obviusoly still powered when igntion is off.

Anyone know if this is correct?

Have you read through these Coxy?

IACV - Removal, cleaning and replacing the valve.
IACV - Replacement guide.
IACV Reset - How to reset the IACV.

Yes mate i have, although not when warmed up.

It doesnt sound like the valve is moving when the igntion is off just the fact that its making a strange whistling noise.
I just though with ignition off the valve would be dead?

could it not be the stepper motor resetting

yeah thats the same problem.

Will take it for a run today.

Se how i get on, i was juts concerned i had wired something up wrong

It's normal; I can confirm the noise is coming from the ICV even when the ignition is switched off. I first noticed when I had my 03 TF and now the same noise on my 05 TF.

Next time you have the engine cover off: switch the ignition on then switch off so you get the noise, then unplug the ICV and the noise stops.

Not sure how long it gets powered but it will shut off after a short while.
