Am confused to which is the egr valve and how to remove it, there seems to be to pieces, its running like a bag of spanners at start up for first 5 mins the whole car shakes till its warm, so what am i looking at here please, seen to be 2 bolts to the right on the pipe 2 bolts on the the 3 maybe 4 holding the two pieces together where there is a long bolt that screws into the manifold

thanks in advance
