I think the winter pack is low screen wash warning, headlamp washers (but these were standard when xenons were fitted), and heated windscreen washer jets. So on yours (and mine), the winter pack was just heated windscreen washers...
I think luxury pack was a dipping side view mirror when reversing to give a view of the kerb (you have to have the mirror adjustment knob turned to passenger mirror I believe), and electric folding mirrors with puddle lights.
