I get around 28-30 consistently. True most of that is motorway, but shows that if you dont drive it like you stole it all the time it will return pretty good figures.
And VAG engines are weird and wonderful beasts. I heard of Leon Cupras being remapped to much higher power and also reported better MPG. The assumption was always that as the toque was available lower down, you didnt have to rev as much which meant better fuel consumption. Not the way it works with most cars, but VAG maps consistenly showed better MPG
