Thanks Kenny & Malcom. I always put the A3 in the garage on charge when after use so should not be too much of a problem, though a charging point would be useful (especially if we end up with a full EV as 2nd car). The A3 has a battery half the size of the NX and it normally takes 3-4 hours from empty.
I downloaded the manual last night and its quite a tome.
Off topic, but I was hoping for Home link for my garage door but did not see it...
