Guys is my 320d being over optimistic or what?
Drove from London to Nottingham tonight and managed to achieve 61MPG reported by the OBD is it a possibility it's been remapped?!
Following on from this I got 708 miles from a tank which I was mega impressed with but real world MPG is actually 52mpg I believe!
Is there a way to sort my OBD being so optimistic or??
