    ADVICE, p0400 fuel malfunction but NO SYMTOMS

    hiya, i recently bought an astravan 1.7 dti but,

    every so often its showing an intermitent warning light (car and spanner) two diffrent people have told me its p0400 -critical fuel pump system malfunction 2,

    before i got diagnostics i thought p0400 was egr so ive cleaned it and replaced it, that seemed to work for 65miles lol,

    however never have problems starting or driving its spot on all the time no juddering, stalling etc but when the light comes on i seem to loose the use of the turbo, thats the only diffrence,

    on previous threads people have mentioned dodgy/blocked fuel pipes and solder joints, i would like to rule out these cheep jobs before facing it could be the pump, let me know what you think,

    and please tell me where to look and what to do as im unsure,

    thanks for your help, Ash
