Unhappy x5 e53 battery drain found but not solved.

hi, I have a battery drain. I have found the fuses that are causing the problem and removed them to stop the drain but cant figure out the problem.

both of these need to be removed to stop the drain.
R3 RELAY IN THE BACK (audio unit relay) and
FUSE 72. (1st in line, the audio/nav fuse)

I have disconnected the navigation unit, the cd changer and the stereo/computer head unit
but the drain is still there until the fuse and relay are removed.

please please any help would be great as I'm new to the x5.

many thanks in advance.

Do you have blue tooth connect for phone? This is probably the bad unit. Unplug it & see if the problem stops
