    Not sure how the lights on your car are assembled, but I'd check that all the clips that hold the unit together are doing their job and that the light is reassembled perfectly.
    I had the misting problem on my Vito and it turned out one of the clips had broken and then glued back together.
    I replaced the whole rear plastic part of the unit (£8) and even then the condensation persisted until I fitted the part perfectly. :eek: No problems since then.

    On a W204 it happens by design according to the handbook.
