Removal of the throttle body/EGR return mixer on Mercedes E320 Bluetec with the OM642 engine. This is part of the job to fix oil cooler seal leak common in this engine. The piece I call EGR cooler is actually the throttle body/EGR return mixer (not the EGR cooler itself). The copper pipe on this intake body (shown at 5:32) does connect to the EGR cooler (shown at 6:28) but the EGR cooler itself is under the driver side intake manifold and attached to it. This is the 2nd video of a series of oil cooler leak fix job: see the playlist to watch them in order (videos are also numbered in the title)
