have a look at this thread

there is a post showing two types of display in post 4.
if you have the display on the left you cant access the mpg, average speed unless
you change your display and change the indicator stalk for one with a button on the end.
you can get another set of diesel clocks from a scrap yard that has the correct display and correct indicator stalk. You will need one of the T4 guys to configure the "new" clocks to your car.
swopping indicator stalk and clocks... 30 minutes. Configuring clocks may be an hour.
you can also get access to a digital speedo which I'm told is more accurate
indicator stalk and clocks cost me £20. what you wont know until you try it, is if the display has lines through it but you may be able to return it to the scrap yard or post in the wanted section for the parts .
