    i have an 2002 A6 1.9tdi 130
    im having a problem i cant seem to get to the bottom of
    whats happening is when i start it from cold it dies and stops again this happens several times then eventually it starts but you have to hold it at 1400rpm ( while at this rev its hunting ) do this for about 4 minutes then it idles fine .
    I changed the fuel filter ,
    then ran a diagnostic where errors for the air mass / map sensor came up i run actual values and these were both reading out of spec so i changed them ( also was loosing power and black smoking so these made sence as errors ),
    I left the car till the following morning and no difference at all
    just wondering if any one has had or no what should i do next as im running out of hair to pull out :)
    thanks in advance
