Good afternoon. I recently purchased a 2012 Audi A5 Quattro, Black Edition, 2.0TDI, manual, with 9000 miles on the clock. Audi claims a combined mpg of 55.4, for this model, and although I know these figures to be generous, my car is averaging 34.6 mpg, whatever the driving conditions and type of driving I do. My commute is a mix of dual carriageway and A roads, and still I am only getting the above figure. Does anybody have any advice, or are people with the same vehicle getting a similar mpg figure? Many thanks in anticipation! :) Steve
