Curious, what's the normal voltage of an X5 when the vehicle isn't running and there is a load? I checked the X5's voltage this afternoon with the engine off but all electrics ON; vehicle has not been driven in a couple days: 11.8V.

The battery was just replaced on 23. Dec 2010. One thing I noticed that's new (compared to before flat battery) is that the P is not illuminated/displayed on the gear shifter until I put the key into the dash slot.
