YOUR EGR SYSTEM HAS SERVERAL PARTS TO IT, WHAT PARTS HAVE YOU ALREADY CHANGED.ALSO YOUR PO420 CODE PERTAINS TO CATT EFF. BELOW THRESHOLD WHAT HAVE YOU CHANGED THERE
401 is an egr code that may be a clogged passage rather than a bad egr valve. stop throwing parts at it and have it cheked correctly.

420 is a bad cat. it must be replaced.
