Hi Gareth, I understand that this topic has probably been dissected to death but I was wondering is there any way to increase my MPG. I currently own an 14 plate A6 2.0TDi and on my daily journey of 100 miles on the M4 and M48, I am only getting around 35 MPG at 70mph. I came from a 1.6TDi Passat that would comfortably get 45 MPG + with a full car and less careful driving. I hope you can shed some light on whether I am being unrealistic in hoping for better MPG Thanks Ryan
