Picked it up yesterday

2001 A6 2.7T

very nice... looks new .. 71800 miles
interior and exterior excellent .. new tires
all factory specified maint performed up to 70K

came with NO owners manual -- on order from audi.
I've figure out almost everyting (all those cool red buttons at night)

what/how does the ESP button work
and how do you get seat memory to work .. and why sometimes when
you get back into the car, the seats are where you left them, and other times
they seem not to be.

and .. how do I change the display mode for the digital display?

more when I think of it .. but man, that car is fun to drive.
