Hi Peter - Yeah, mine is still working fine (really ticks me off that the
dealer replaced it rather than doing this adjustment... $230!!!).  Anyway,
I can't emphasize two items too much: 1) *everything* else has to be
operating properly; i.e. this should be the last thing you adjust because;
2) the adjustments are extremely sensitive...a little does a lot.  As a
test, since getting it where I want it, I've moved the screw back'n'forth
1/4 turn, and am able to re-create the symptoms that we read repeated so
often on this list.

p.s. - keep in mind this is an '87 Digifant system...I'm not familiar with
other Vanagon setups (but I can do a Rabbit CIS blindfolded!! which will
probably get me a cuppa???).
