I've had my gti pp dsg 5 door for 3 weeks and am averaging 28mpg. In fairness when one considers mostly local town driving, winter time, new car and getting acquainted with car, for the type of car it is I think is what can be expected. I travelled on dual carriageway road for about 27 miles to a retail park and recorded 37mpg. On the way home I recorded 40mpg. Come spring time and when the engine is not so tight I will be looking forward to an improvement in the mpg. I've only covered 300 miles in car so far. It's a brilliant car. My previous car was an audi A4 2.0 tfsi 208 bhp where I recorded an average of 38.1mpg. I would expect similar in my gti in time to come
