What Is This Part For?

As you can see, the EGR valve (far end) and the manifold are clogged up.
No I can't see they are clogged up and you never said which is why i'm asking. Don't worry about it though, it's a recurring theme on here, we like guessing games.If I was to make a not very educated guess i'd say there will be a type of throttle flap inside the plenum which it is actuating. I think what happens is that at certain times it closes off the fresh air so the engine induces exhaust gasses as well or instead of.
I think your engine is fitted with swirl flaps and there will be an actuator for those too, but I don't think that is it. There is a feature representation on the net somewhere by the makers, it goes through some of the technical aspects of the engine, it may be on there.

EGR feeds exhaust air which dont burn inside the combustion chamber, but it cools down the mixture to avoid nitric oxide forming.
So from what you're saying and what it is in my engine, the fresh air is fed all the time but EGR valve kicks in at certain pressure, like when speeding..
Yes it's an anti speeding device. If you go outside of the speed limit your engine gets clogged up and slows you down.So from what you're saying and what it is in my engine, the fresh air is fed all the time but EGR valve kicks in at certain pressure, like when speeding..
Always drive within the speed limit.

Does the car have cruise control?
If so, I think this is the throttle for that. There's a diaphragm inside the container hat should be conneted to the intake manifold to sense the vacuum.

Yes, the car has cruise control option but it's not working at the moment due to faulty speedometer speed sensor.If so, I think this is the throttle for that. There's a diaphragm inside the container hat should be conneted to the intake manifold to sense the vacuum.

I can't quite understand how this would relate to cruise control though

Thanks
As it's drive-by-wire (DBW) system, CC is controlled electronically. It's a known problem for this model and it needs is replacing the speed sensor at the back of the transfer case
