My GTD 1400MILES and had it since 24/12/13.... to be fair the car felt more together about ten days ago, it just felt not like a brand new stiff car but more running together in harmony...main dealers had to reinstall the software last week as the dash was bleeping and lights coming on...it seems to be giving me slightly better mpg...I always have it in sport...average around 42mpg....im ok with that, although the courtesy car given to me was the 1.6d 105ps dsg and I ended up doing around 55 miles, didn't put a drop of diesel in when returned as the needle was still showing full.....I think 50mpg + are only achievable in the 105ps model...now way you are going to be in a bright red gtd and driving it where cars are thinking of overtaking you because your just not accelerating.
