I know you can reset it and have done, but it is clearly showing wrong - with even after a long motorway cruise showing both a much too low average speed (e.g. 25-30mph) and a low MPG (c.45mpg compared to official combined of 58mpg let alone motorway mpg!) and the figures will only climb very slowly). Is it possible to get it corrected, and if so how does one go about it and how much does it cost?

you might be able to fool it into resetting if you disconnect the battery for a couple of hours???

BUT make sure you have your radio code.coz if you havnt you wont get it from here.

I think you may find it to be correct. Please bear in mind that it is a calculation of average, over a period of time since it was last reset. It also factors in all the time spent at junctions, traffic lights, traffic, etc, which drop the average down. Even a few mins of stop/start will bring the average right down.
