i have found my fwd tdi to be great in the snow, interesting reading other peoples findings
i in the past have had my esp on, but saturday night i was going up a hill and was loosing speed till i was at a crawl, esp light looked like it was having a fit, i then saw lots of other cars coming up behind me while im doing 1mph lol.
after what seemed like a long time i got the abs, esp, handbrake and a big brake symbol come up on the dash, i thought this was going to cost me,
the esp had trip out, it then seemed that i made more progress to the top, i turned the engine off and back on and the clever audi had fixed it self, nice!
so think its true that esp can slow you down,
