The MPG readout on my MFA says 99.9 all the time. Anyone got any ideas why or how to fix it? The other readouts seem fine.
check the pipe that goes to the back of the clocks. think it comes from a valve in the brake servo pipe. it may have come off or split. if its the clocks that have gone,you can try leaving the fuse out overnight and this sometimes cures it,they are expensive to have repaired.
