But, the meter was connected and turned on for those 20 minutes, correct?

You should see a higher draw when first connected, and then it should drop after 20/30 minutes. Did you see something higher than 0.34A to start with that then dropped some? If so, that would indicate that at least some of the modules are sleeping.

I wonder if there is any BMW tool to plug into the CAN bus with the car off that would tell which, if any, modules aren't sleeping when they should be? I know at least one other car brand that has exactly this for exactly this sort of problem.
