Hi folks. Just wondering what the real world average MPG figures are on 2.0 TDI 140bhp engine for the A4? I'm looking at a 2009 A4 Sline. Parkers guide has it quoted at 56mpg Audi A4 Saloon (08 on) 2.0 TDI (143bhp) S Line (Start Stop) 4d - MPG, Dimensions & Performance | Parkers Should I be expecting to get close to this figure with majority of driving on motorways? If I'm down around the 49 mpg mark, does this point at problems somewhere?
