The diesel camper is a noisy machine, but with that being said; my camper
was missing the rubber hose/bellow that bridges the gap from the air cleaner
to the air snorkel in the side wall of the van.  It did make a difference
overall to the point where it is more manageable- at least I can carry on a
conversation now if I speak up.  I ordered mine new from vw a few years back
and I can't remember the price but I'm sure it wasn't cheap. I think it's
worth a try to replace or improvise a replacement hose.  Joel Hembel - 82
