Where do Audi get their MPG figures from. Previously I had a 2006 1.9TDI which had MPG figures of 50+. I have since bought a 1.6tdi with estimated MPG to be around 65/68. I have now done 1800 miles and the DIS tells me I am averaging 49MPG. My pump receipt tells me I'm only getting 46Mpg's!!!! I have been driving like James May from top gear for the past few days and I'm still struggling to get over 50MPG. Can anyone tell me how to get the best economy without rollercoasting down hill, or is Audi telling us porkys?
