I fitted a restriction gasket to my egr pipe and now in the mornings i hear it hoss a little when the wgr is open this dosent borher me i read my vcds readongs and egr spec should be upto 300 and my actual was like 450?! Is that the gasket or is my egr playing up? Seems to drive okay and sorts. I have striped it down and cleaned that and my inlet manifold from all te gunk!
