oh dear. this is a common problem on your ml. that is a part of the manifold shut off flap system. when the turbo is under boost you can hear the air escaping from the hole left behind. when you disconnect the vacuum pippe the turbo no longer boosts intake, so no more escaping air, no more noise!

the short of this, you need a new manifold i am afraid.
