Power Loss In 3.0d 2004 facelift

[omodos]

A big hello to all from across the ocean and hope all is well, please can anyone chime in as I am a tad concerned, I floor the gas pedal and instead of taking off and hearing the characteristic whistle of the turbo its as if I am driving my old mercedes 190e , its become a cruiser! no oooomphhh



Back in 2008 I had the same issue but it doesn't seem to the same now alas, fix back then was the one end of the piping (arrow in pic) had come off what i think is the wastegate as in picture...the same pipe now is a bit frayed on the outside being braided with cloth rubber but doesn't seem split or cut, when i pull it off the wastegate i do still hear a small hissing noise, same on the other side too as there are two separate pipes on that black ball which is the wastegate ?


Should the item in photo allow full passage of air through it? I have no idea, all i know the turbo isn't kicking in now, has 96000 miles on the clock, if my turbo is dead would there have been any tell tale signs?
any input much appreciated
