hello folks, the two identical vacuum module things mounted next to the air box and underneath the egr. i was changing hoses and got mixed up i think.

can someone take a look at theirs and tell me, does the module closest to the FRONT of the car go to the egr valve? or the intake flapper?

thanks.

Model and year, please. I'm guessing '96-97 W210 because the '95 W124 uses an OM606.910 but humor me please so I don't give you wrong information.

Jeremy

yes thats it 1997. i just got it figured out though thanks. one way makes instant cel with p0400 egr malfunction. the other way doesn't.

front most vacuum module goes to egr valve. rear vacuum module goes to intake flapper.
