    3.0tdi Quattro auto fault code.....



    I keep getting this fault code coming up ..... Any help anyone ?


    symptoms are, driving in sport, progressive acceleration, 3rd to 4th and 4th to 5th, top end of the revs it rumbles/judders for a couple of seconds then sometimes drops into the next gear, sometime I have to back off the throttle then reapply to get it to engage the next gear

    I've had the box checked, the oil is of good quality and no water ingress - the oil level is satisfactory too

    trying to get a heads up here.....any help ?

    There are no other fault codes in the car either, nothing in the engine ecu ------ :/

    Turns out it was an issue related to the fuel system

    Every two seconds after the low fuels pressure code flashed up the gearbox fault was logged
    Then the low fuel pressure fault vanished from the ecu

    The cars had a complete fuel system bar the tank and on fuel pipe as per a TPI from Audi - I've done 1000 + miles and its faultless
    the cars slightly better on fuel and the performance is back
