Fuel Injection FAULT !!

[pegbox7]

Hi there,

has anyone got any ideas about this ?

Car is a 2001 X5 3.0 Diesel, drives normally until you open up the throttle then a message appears accross the screen on the dash saying " Fuel Injection " this is followed by a massive loss in power as the vehicle goes into limp home mode. if you swotch the car ignition on and off it restarts without the fault but does exactly the same as before when the throttle pedal is pressed down more than half way. The car can be driven on part throttle no problem at all. The car is regularly serviced and has clean oils, filters and decent diesel in her. Any clues before i spend a fortune at the main dealer ??
