    Hi Patrick,
    Thanks for this great info. I too have a 0.4A draw on the 'Dome' circuit. I can't be bothered with trouble and expense to replace the Combination Meter but if it does turn out to be the culprit do you think it would resolve the problem if I traced the power wire to the Combination Meter and spliced a simple on off switch into it, which I could mount on my dash, so I could turn the power off before leaving the vehicle.
    Thanks
    David

    I suggest you look for a stuck relay first.

    Update - I didn't have a parasitic draw after all. It turns out just checking the circuit when everything was asleep woke up the circuit and created a the draw.
    Thanks everyone for your invaluable help and advice.
