That bar thing is the valve lol....theres a plug on the bottom of the bar. When the bar moves up, exhaust is allowed into the intake.....especially at idle to remove NOx, theres not so much NOx produced when you rev it a bit so the valve closes partly.
If theres smoke goming from it, its probably leaking from one of the gaskets (exhaust side I'd guess). If its almost hanging off and blowing lots of smoke that could be your boost leak....but I doubt it'd be that bad. The EGR was leaking on the old golf and there wasonly a little whisp of smoke when booting it lol.....I've completely removed it on the new golf though.
