off the top of my head and a fault i,ve come across befor is the metal contacts in the boot that control the int light. they get corroded and the pins get stuck so it might be worth avin a little look.
Good idea, but the problem here is that this is a fault which doesn't show if you connect a multi meter for a few hours with a "snapshot" approach to finding the drain, and yet is enough of a drain that the new battery only shows c. 5.5v after 2 or 3 days of the car standing idle, which means that it must a considerable drain given the 120Ah ( exact size ? ) battery in the boot of the 540iVee said:

Traffic master module has now been isolated, problem has not reoccurred, thank you all for your advice
