How do I check if the WG is broken?

[PERiskop]

Hi!

I'm quite sure that my wastegate is broken since the boost pressure is going through the roof when I put the pedal to the metal Is there a way to check if it works properly without taking it out? If not, how do I disassemble it?

Thanks...

see if it's holding a vacuum or stuck with a vacuum guage

If I have the engine turned off, am I supposed to be able to move the WG-arm to the valve? I've tried but it seems stuck...
