    check all the vac pipes etc... the rubber connecting ends split throwing the same fault code.
    Also check each glow plug to see if it's heating up, although the pre heating system is not used in temps above 5*

    i cleaned mine and it only lasted 200-250mile before it gave up completely. i got the EGR valve from ebay for £215. fault sorted after that.
    but,
    i would do all the pipes first, replace all the rubber connectors and t-pieces, if that doesnt fix it then EGR or acctuators are goosed.
    acctuators are the bits the pipes connect to, check these have a vacume by wetting your finger and placing it on the acctuator vacume output (its labeled on the top) while the engine is running. you should be able to detect a vacume with a wet finger, i thort i couldnt so replaced the acctuator and still could only detect a tiny vacume so left it like that.
    any questions just ask.
    mick.
