Sorry for my basic explanations

The car isn't boosting at any revs, at least I can't feel anything or hear anything.

I disconnected the hose (highlighted in yellow), which goes to the bottom connection of that valve. This has a vacuum. When I block this, the actuator arm rises, when I unblock the actuator drops.

Reconnected yellow hose.

Disconnected the orange hose. No vacuum on idle or on revving in neutral (no load). The arm on the back of this (egr valve?) moves freely.

On revving the actuator spikes v quickly once and rests in low position.

Any ideas?
