Hya,

 

Can't help you on the 99.9 mpg, other than its fubared or you are driving very very slow. MFA 1 and MFA 2 I can; MFA1 is a trip computer per journey, it does take into account stops, it also self resets but I don't know the time period before reset. MFA2 gives roughly the same information bar for its an accumilation of all your journeys so if mpg was wokring the 2 should post different figures as will your average speed. Both can be reset by pulling slider towards the number.

On the back of the clocks there is a tube connected that feeds a vacuum to the clocks for the MPG telling them how much fuel is being used, this has probably come off, it just pushes back on.

What's wrong about the speed? is it jumping about? If so there is a sensor on the gearbox, assuming your car has a digital odometer readout not an analog scrolling one, if it's analog then you have a cable instead.

I'm glad someone else has had this problem. Mine was doing the same, so I'll be having the clocks out tomorrow to get this sorted.

You dont have to take the clocks out, to get at the hose all you have to do is take the lower panal of and get up behind the clocks, as you cant put the pipe on then put the clocks back into prostion as the bit of pipe I don't thin is long enough. Save you some extra work
