W211 OM642 EGR Removal

Removing egr from a 2007 S211 om642 engine to give it a clean. Tools required, hammer, 20mm wood chisel and a file to clean up the bur you will leave on the egr lip. Used parafin to give it a quick clean but to be honest after 125000 miles there was not that much soot in it, i think all the real gunk is in the intake manafold.
