2008 R56 something is drawing down my battery!
 

Car goes to sleep in about 15 seconds(as it should), all interior lights go out etc.

but

If you pull the neg side of the battery something is using 10 volts of draw.
also
When you put the neg side back onto the battery it is a big spark!
(lot of draw)
We removed the power supply to the fueses under the hood and there is no spark there so whatever it is appears to being drawn from the fuses at the passenger footwell.

I assume all the computers to the car plug in at this footwell fuse box, i was not able to unplug the 5 or so of those.

I removed each fuse one at a time and watched the draw and nothing changed. All fuses are good.

We also removed the power supply going to the alternator and its not that.

Only codes are from a tpms issue and i wouldnt think thats it.

HELP>>>>>>>>>>

Remove the positive cable and install a digital amp meter , get the amp reading.
Then start pulling fuses individually to see where the big draw is.
After that you'll have to troubleshoot the circuit

Done, its only drawing .44 with the meter set at 20amp...not sure if this is what it should be drawing or not? Maybe it is my battery? Pulled every fuse inside and under hood...didnt really find any fuse that made much of a difference???? Soemtimes i would pull a fuse and it would go down a litte and then other times when i put them back in it went up.

.44 A is likely normal clock/computer ect Might be bad/weak battery or connectors
