just done a little over 4000 miles since I got the Grand Sport and a message has just flashed up saying I have 1417 miles left in adblue tank.
I'm assuming it was filled up when I got it (tho wouldn't bet on it) so I figure that makes it about 5.5k per tank full?
How does that compare to all you other 2.0TD GS owners?

PS I get adblue for £6 for 10 litres trade, spotted Carplan 5 litres in Asda for £5
