My car has got a really annoying idle, especially when it has cooled down below normal temp sometimes. It will vibrate quite a fair bit and I sometimes find myself having to (1) either floor it when it's hot enough to get the idle to a more smooth level (ii) sit at the traffic lights with my foot on the brake and a little gas on the accelerator. With the second option it sometimes feels like my car has a low hum particulary with the A/C on. After a while she behaves and no dramas.
I have noticed that in the mornings it goes to about 800rpm and by the time I am down the road (about 700 metres) it has almost fully warmed up and the idle is at 600rpm. It can be so annoying sometimes that I can put the car in reverse (after I have started it up), reverse out put in neutral it vibrates annoyingly and put in drive and off it goes.
However I am confused and just want to make sure I am looking at the right thing in my engine bay. I have circled it in this picture. Is this the thing I am taking out and going to give a WD40 clean with? If so will do it and this should sort the problem out (if I did an ECU reset as well, this fixes it for a while).
Sorry about the dirty engine bay, but she recently came back from a trip down south.

yes that is the iscv, i would clean it with throttle body cleaner or something like that rather than wd40 also has a few coolant connections attatched that can sometimes be rather annoying to get off and on.. i just cleaned mine to no avail chasing a bad idle problem

Just bringing this up again, I assume when I detach this from the car, I will have some coolant leak. Is it a fair bit or is it just going to be a little bit. I have read that a top-up will be required, but have no idea how much of a top-up is going to be needed.
Can I block the pipes that lead onto it, give it a quick clean and then chuck it back without losing too much coolant?

You shouldn't lose much. Feel free to put a joiner in to bypass the coolant around the ISCV for the future. Also saves you losing coolant again when you go to clean it next time.

Another question is there a difference between the V8 and the TT's ISCV?
I have found these pictures (through searching on the forum) and confused as to why mine doesn't really look like them. It seems I am missing the screws on the black part that is attached to the base of the whole unit.

actually i just took mine apart and cleaned it but you cant take the black motor apart only it off the aluminum housing and clean it... there is two cylinder shaped parts on the housing with a hole in one side of each and not in other. the side with the hole has sealer in it. get a 1/16 drill bit and drill straight through center to get the sealer out of it(should be white) and drill through until it comes out the aluminum housing in the back then get a 1/8 inch drill bit and drill the housing where the other drill bit came out. then get a 1/8 inch punch and knock the roll pin out of the housing(two of them) and twist the black motor off the housing. to put together just seal the motor again stick on the housing and put the roll pins back in and reseal the holes.... done
