    I had a serious fuel leak. It came down to a faulty gravity valve in the tank. The valve left it self stayed open so was spewing out fuel from the filler cap area due to the massive pressure build up behind it.

    Areas to check -

    filler cap
    behind the right wheel archliner
    underneath rear bumper
    fuel filter

    The valve cost @ £3.00

    However it meant a fuel tank out job and 4-5 hours of Audi priced labour...ouch.

    Hopefully your's is just a fuel filter change job!
