P0400 error code on 96 E-320
Can anyone tell me where the pipe is located off the EGR valve I need to clean and how to go about it? I've replaced the fuel cap and checked the vacum line at the front of the engine (and that line will break at the slightest touch)

MBWorld Fanatic!
Replace the tube first,if it is that brittle
it may be leaking.
Don't have the WIS handy for the M104
I did a diy on the m112 on benzworld.org that is similar from the egr on down.Or search the diys on mercedesshop.com someone did a m104 egr awhile back.
always check hoses and fittings first.
www.autohausaz.com for a new egr if yours is shot.
old vacuum operated ones can be cleaned in place.
some stores carry a new tool called snake bit or use an old speedometer cable in a drill to clean the tube.
