Emissions Issue FIXED! - Mercedes S-Class EGR Valve Replacement (W220)

My 2004 W220 S-Class had an EGR error code, so I replaced the EGR valve and pipe to get it back on the road! Along the way I found a couple damaged vacuum lines that I also took care of. Overall, it’s not a bad job, but you’ll need a wobble socket extension, some E-torx sockets, and a 25mm crow’s foot wrench to make it easier.
