1.9tdi AHU not starting unless boost control valve unplugged

Howdy,
At a bit of a loss so thought I’d come to the well of knowledge.
Tried starting up ready to drive to my MOT and no joy.
Well, it cranks and starts fine but runs all of half a second before cutting out. Had a look in the engine bay and could hear the turbo boost control valve clicking fast, unplugged it and starts fine and drives just slow obviously.
Any ideas? Only thing recently I replaced a fuse for the heater fan(and switch) and fog light that’s all for the electrics
I’ve had issues for a while with massive power loss, feels like my old 1.6d, but I’ve narrowed it down to what I assume is bad injectors as I’ve just replaced the muffler and it left a mound of soot on the floor.
