We've been over this before, remove intercooler and look into the intake and you'll see said butterfly.
Worth removing EGR valve and cleaning it out at the same time but its obviously important no swarf goes into the intake, you'll have to drill the 2 small screws out that secure the flap in order to slide the flap out of its groove.
Do not disturb or damage the spindle because that needs to operate to trick the system that all is working correctly.
