    Known problem with early models, only long term solution is a new headlight. I had the same problem for ages, and I just took it out and blasted it clear with a hairdryer, and that seemed to do the trick for a while.

    Took my factory xenon headlight moisture issue to the dealership. They said moisture was normal as they are "ventilated" and did not need to be sealed. Bunch of crap if you asked me.

    Xenon's have to be ventilated due to the heat generated. Steaming up is a common complaint, but perfectly normal, unfortunately. Don't completely seal them!!

    There is an Audi technical doucument somewhere that states the tolerances on how long it takes the moisture to evaporate after the healdlight is switched on - i.e. how excessive is the moisture. If it takes longer than stated, then audi will replace the headlight.

    MadVW's right !!
    Heres an extract from the TSB

    + Exterior light assemblies (headlights, taillights, fog lights, turn signals) are vented
    and may collect moisture on their inner surfaces, depending on humidity and other
    climatic changes.
    For headlights, the affected lens surface should be clear after approx. 10 minutes of
    light operation, although the entire surface may not clear.
    ________ Note:
    Condensation does not affect performance of
    light assemblies.
    In cases where larger water droplets have
    formed on the inside of the lens or significant
    amount of water has collected at the bottom
    of a light assembly:
    Check for leaking seals, cracks in lenses or assemblies.
    DO NOT replace light or lens assemblies for
    this condition (unless damage is found).
    If damage to seals or cracks to lenses or
    assemblies are found:
    Follow normal repair procedures for this type
    of failure (provide a photograph, if possible,
    with repair documentation for verification).
    If no damage is found, use compressed air
    (less than 30 PSI
    ) to blow out the lens.
