<< The air conditioner vents on my '87 Westflia have suddenly started
 spewing black foam - small chunks of some sort of semi-deteriorated
 open-cell black rubbery stuff.  It looks like the remains of a filter of
 some sort.

 I've looked in the vents and the air inlet with a flashlight, and I don't
 see any filter.  << SNIP>> Or I should just wait for it to all blow away? >>

Welcome to the world of the 11-year-old VW.

The black foam, that now will be part of your motoring life for a couple of
years, is the remains of various edges and insulation from the air/heat
system. Most notably, this stuff was around the edges of blend doors. My '85
started spewing foam a few years back, and most of it now comes out as powder.

It doesn't seem to cause any lack of performance, although when I have the A/C
set to "small snowflake, only in your face" I feel some leakage, as if I have
it set on "snowflake in your face, and on your feet".
