    a4 2.5tdi very bad starting missfire/stutter 1800rpm?

    my a4 has never started great but always fired on 5th turn, now its spinning over 30 seconds before it fires up with a cough and loads of smoke

    checked intank pump by powereing fuse 28------- all ok
    replaced cooland temp----------------all ok
    checked power to glows------------all ok
    new diesel filter-------------------------all ok
    checked cams for wear all seem ok
    code read----------------------------no codes except egr recirc due to blanking plate
    its a 2.5tdi 163 cab manual

    no im at wittsend with the thing, the car always has had a bad vibration under acceleration like 2 cv joints are gone,also driving steady about 1500-1900rpm it stutters and holds back and when you accelerate it on boost its perfect

    could it be a dualmass?
    pump timing? can i adjust this myself manually or is it vcds only
    pump issue?

    anyone encountered similar

    Pump timing might be out, get someone with fully registered VCDS to check it for you and adjust the timing towards the top line...
    Chances are the timing it's so advanced it might not even show on the graph at all !
