Thanks you for the exloration you made.

I am sorry that you could not move that screw to see its function.

If I understand correctly, when at idle or at engine OFF, the shutter is in the default position.

Unfortunately I do not have a non working ICV to open it and see what the inside looks like.
I know from some drawings I have seen there are 2 bearings and one spring that could fail (+ other electrical devices indeed) and I suspect them to fail with ageeing.

Would you have the interest to open the ICV I would be interrested to have some pictures and try to imagine if the ICV would be reparaible.
I am convinced that it is interesting to know how these smart and expensive device work to unsderstand how to repair.
