I generally agree. But what? I already mentioned my EGR valve holds vacuum just fine, but I suspect it may be EGR related as well - I just don’t know what. In all fairness, I’m not terribly knowledgeable on EGR stuff, so EGR pro tips are certainly welcome.
(edit)
This picture was taken with a potato, but this is my EGR system according to my underwear manual (Haynes manual).
