I don't think so. AFAIK, the normal output for heat in ECON setting
is directed at the floor vents (maybe a little at the defrost vents).
The normal ECON mode of "heat-to-feet and fresh-to-face" has
generated longstanding gripes from (American) Audi drivers who tend
to dislike the cool (cold?) fresh air coming into the face from the
dash vents when they're calling call for heat--it's something the
Germans evidently believe is useful for keeping you alert, I guess.
The low temperature (gauge) readings Scott described are pretty
common for this car and nothing to get concerned about, IMHO. But
Scott states his need to have the heater setting in "mid 70s" and
that sounds quite excessive to me (knowing where Scott lives) and
suggests that he might be getting insufficient heat because of
malfunctioning heater (control-flap) feedback potentiometer. Has that
been replaced recently? Common problem area.
Scott, does your comment about "low coolant level" possibly refer to
the fact that you've been getting the coolant warning signal????? If
so, then there's surely a problem with the MFTS--considering the
other symptom (low boost) you mentioned. Are you certain the contacts
are good? Was the replacement MFTS you installed recently a *new*
one, or did you waste your time following the philosophy that "old
cars don't deserve new parts"?
