IC Hose comes off... put it back on and I'm not so sure

[Ed Kellock]

I do recall hearing about something in the plumbing to dampen the whine of
the turbo.  I recall that my 89 200q was quieter than my previous 91 20v and
then later reading about how they put something in there to quiet the turbo
whine/whistle.  I always wanted to go in and remove it but never did, so I
can't confirm whether I had one or what it looked like.

Nothing in the entire intake system from air filter to the intake manifold
has a "foam filter in the middle."

The only thing I can think of that could match your description would be
part of the crankcase breather system.  That hose does commonly fail with
age, turning mushy-soft and either collapsing or breaking apart.  If it
starts leaking, it introduces a big vacuum leak.
