I've done about 1,700 miles now.
ABS - light comes on at start but behaves itself and goes out appropriately
Coasting - not something I tend to do but had no issues with clunking
Diff lock - used a moderate amount and, again, seems to work just fine. The usual lag for off but thats always the case.
6th gear - fabulous when I need it, but nearest motorway is 50 miles away.
Gearbox heat - not noticed any. Have done a few two hour trips including some motorway and it's been fine.
Issues I have:
Heated front seat - very slow to heat up compared to my D3. God help my arse when it's -10C.
Two of the lights, a front side, and a rear indicator, looked like the bulbs had failed but the connections were just loose. Quickly fixed by me.
Offside headlight has condensation in it. Just noticed this tonight. I'm not familiar with the unit. Is this a dodgy seal or something terminally wrong with the unit?
Other than that it's fine (he said, tempting fate) and a joy to drive.
