    Default

    it's under the black plastic engine cover.. remove that, the top air intake hose as well.. then you can remove the 4 bolts that hold the top part of the manifold on..that will reveal the part of the manifold that lets the EGR gases back into the engine... there are 2 water lines and 1 electrical plug to undo on the block below it.. that block is the EGR valve..2 bolts secure it.. undo the bolts, wriggle the EGR out and it's off... i use carb cleaner to decoke them, along with a small softish brush..
