1. Do the heated seats work at any outside temperature when turned on?

2. Do the heated seats get warm all over the seating area or do they respond to the pressure of where you are sitting.

Speaking about my 96 A4 only:
Yes you can heat your butt at any outside temperature, and they do seem to work whether you are sitting in the seat or not. I've never noticed any area other than the bottom cushion getting warm. Your mileage may vary.

All surfaces seem to get warm, and the steering wheel.
