Probably an eco thing since when it is in cupra it holds gears longer anyway.I have done nearly 1,000 miles now in mine and I have been really impressed, a few long journeys over Christmas and it's a very good all round car. Went from London to York and got 37.2 mpg on the way up and about 33 mpg on the way back. Short journeys in town are normally in the high teens on the mpg, but hey we didn't buy this car for the mpg figures. My only real moan is something I have seen a few complaints about and that is the fact that when you want to accelerate, even lightly, the DSG feels the need to kick down a gear which I really do not like.
Same thing happens in my brothers M140. I got a bit of a shock yesterday when I went to speed up after a lorry pulled in on the A14 and dropped from 7th to 4th and ended up at 100 mph before i got past the lorry.
