    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 !

    I have travelled down from leeds this saturday and can thoroughly recommend him he's fair and thorough.
    I have used him a few times and also asked for his avice before buying a 2.5 tdi quattro.
    This guy knows them inside out .
    Also great wealth of knowledge if you need to pick his brains too
    Thanks

    If you cant make the trip and adams is happy to advise you over the phone id be happy to plug you in. im in doncaster quite a bit with work but dont have too much experience with timing issues.

    However, I travel nationwide to help others and get help, im due in devon on 15th september to meet up and get some advice from somebody, going by adams feedback it would be well worth you taking a day out :D
