Well, tested the Bluetooth dongle a few times, and it gave me a max drop from 0.43 amps down to 0.38 amps. Not enough, but still good to know.

I am now testing the bcu and lsm again, and leaving a minimum of 1 hour in between. Disconnect the one, connect the other, wait and measure. As far as I've gotten right now, I am still very much looking at the BCU being the culprit.

Would anybody know if a BCU can cause this problem? Or does it need to be something that is connected to the BCU, but is not wired in on a fuse?
