Recently acquired a 1992 929, am giving it a tune up. It needs the EGR valve cleaned, but the problem is, I can't seem to find it, the location is either not obvious or it is hidden very well in plain sight. If anyone with experience can point me to where it is physically located, I would be appreciative

 

Found it - man they couldn't have made it much harder to see... Going to put off cleaning it until I do some more major engine work!
