Dead Battery - Servotronic the culprit?

This past Sunday morning my 2003 X5 needed a jump after sitting in the
garage overnight. It needed to be jumped again Monday morning, Monday night
after work, this morning and tonight after work.

I removed the battery and had it tested tonight. No problem found. I'm
assuming the charging system is working fine as I'm able to start the car
three or more times after driving 45 miles home from work.

I reinstalled the battery, left the negative cable disconnected, put an
ammeter in line and measured 4.5A draw with the vehicle and all accessories
off. This seems particularly high to me.

I started pulling fuses to see if I could isolate the problem and discovered
the draw dropped to .5A after pulling the fuse for the Servotronic. I
reinstalled the fuse and the current draw increased back to 4.5A. I read
that the Servotronic module is used to provide variable ratio power
steering.

Is a 4.5A current draw with the vehicle off excessive? Could a failed
servotronic module actually be causing this problem? Does anyone know where
the servotronic module on a 2003 X5 is located? I'd like to replace it
myself since the vehicle is out of warranty. I just paid $300 plus last
month to have the final stage resistor replaced in the a/c. Can I drive the
vehicle without the Servotronic's fuse installed?

Thanks in advance!
