how do i remove the egr valve from my espace?

how do i remove the egr valve from my 3.0 dci V6 diesel Espace - I have an intermittant lack of power usually when warm and would like to eliminate the egr valve from my list of possibilities - I dont need to take it to a garage as im a fully trained tech with 25 years experience but cant for the life of me see how this valve comes out - its a denso unit if that helps
