Check the usual like your final stage?
Have a meter that makes an audible alert if it goes over a set range? (i.e. 0.02A)
I would start with pulling fuses of main components that are unneccessary, like the NAV, IHKE, etc.
Another thing to consider but I don't have a lot of information on right now is that there was something somewhere once when I worked at BMW that talked about a certain component waking the CAN bus randomly. I don't remember exactly what it was but for some reason I think it was due to a faulty Nav computer.
