Bungi, the EFI message on the clocks is to let you know theres a fault.
To get the codes up you need to press the left hand button on the clock assembly and keep it pressed when you turn the ignition on - the codes then are displayed. the actual error codes are shown, i think, in the bottom right of the LCD display (the bit that usually displays the air temperature and voltage) if there is more than one error code it will scroll through them and repeat the sequence until you take your finger off the left hand botton on the side of the clocks.
if you need any more help please U2U me.
