I have a 1995 e320 wagon. I just went through the the vacuum system and checked out the emissions valves. All seem to be ok, but every once in a while I get an EGR code. When it happens it is just after I have started the car. Can be cold or when it is all warmed up. The EGR valve functions ok. I have wondered if the vacuum change over valve could be a problem, but not sure. Any thoughts would be great.

If you're gettng a code 5, then it is almost always a clogged EGR pipe. The pipe builds up gunk where it connects at the intake manifold.

Do a search on how to roto rooter the pipe or replace the pipe.

EGR valves hardly ever go bad on MBs.
