Only 4 little 12mm nuts hold the wastegate on. It would be a good idea to remove it and carefully and slowly give it some air pressure and see if the valve opens.
It should retract or move inwards off it's seat.

You can use a blow gun, but don't hold it tight against the hole - put it next to the hole and slowly close your fingers around it while letting air escape all around so you don't over pressure it and rip the diaphram.

An air pressure regulator turned way down is a good idea if you have one. You only need around 15-16psi to open the valve with a 1 bar spring in there.

If it doesn't open you know the diaphram is toast.
The valve guide lasts a very long time but eventually wears out too.
