Posting to both the A4 and S4 list....
I'm curious about the difference between the quattro systems (electrical
gizmos) between an A4 (I'm specifically thinking '98 1.8Tq (no ESP) and
an '01.5 S4 - 
I'm wondering if when I turn the ESP off on the S4 I'm left with the
exact same system my A4 had.  I've been driving the S4 almost
exclusively with ESP turned off - especially in the snow - as its more
fun and I like to think it sharpens my skills.  My A4 (chipped/exhaust -
NO ESP) seemed to hook up a little better than the S4 (chipped/exhaust -
ESP OFF) does when accelerating in snow - and I'm not sure if its due to
different electrical gizmos (EDL etc) or the fact that the S4 has so
much more power - and also likely slightly less grippy snows - the A4
had Nokian WR and the S4 has Hankook 300 - very similar tires - but I do
think the Nokian is slightly better in the snow....
anyway - thoughts? musings?
