Mine ('02 115 JTD) will reset on the move, no need to be stationary.
I don't bother with the MPG readout any more, I prefer the 'Range' function.
It reflects the MPG you're getting better than the MPG readout.
I also don't fill right up any more, I only put around 20-25litres in from empty.
Not so much weight to lug around, and it's sods-law that if you've just filled it right up to the brim at £1.40+/lt, you'll see a garage with diesel at £1.35 a few miles later :bang:
