If u have the heat shields off, u should be able to push them shut a lil bit - though it will be quite difficult

A leak in the inlet system is more likely than a stuck wastegate. Check all your hoses and connections.

Hmm, you'd still see *some* boost if one of the turbos went I'd say. How did you check the wastegates? It's one thing for the hoses to all be fine, but that doesn't tell you if they are working at all. I gave mine a good coating with RP7 and used an air compressor with a gun attachment and pulsed them to make sure they weren't sticking at all. Still doesn't explain no boost at all

i could move them with my hand and hear them seating again.
Under the pressure could one be opening straight away.
They were pretty hard to move.

there should be a bit of spring pressure holding the wastgates closed? perhaps fire up engine while you look at them and see if they move when the engine isn't under load?
cheers,charles.
