   I don't believe that the Coupes and 4000s do this (my 4000 didn't). The fan can
   run up to 10 minutes on the 5000s. The intent was to improve hot starts. Note
   that there is an ECO for the 86's to add the 'feature'. This feature probably
   results in batteries going south more quickly.

Only in an Audi; the low-speed fan only pulls a "few" amps ("5" on my UrQ)
and will charge at four-five times that even at idle. Assuming you run the
engine (preferably even driving the car somewhere) for more than a "few"
minutes at a time (and assuming you don't constantly drive with the A/C
on and high-beams on and rear-defrost on, with kids in the back constantly
seeing whose window rolls up and down quicker (my UrQ's driver's side is
consistently faster, although I'm the only kid in it, so I quickly tire of
this amusement), there's no real excuse for this to "result in batteries
going south more quickly". But, as I admonished above, this is an *Audi*
we're dealing with . . .
