We don't know the exact amp draw when all modules are in the sleep mode. We will need to get a car in with CA to validate the current draw.
Note: Unless your daily commute is 20-30 minutes or longer on the highway, don't expect your battery to be at 100% charge. A 135i that was just at my shop with an oem battery driven from SF to SB, 70% charge! My personal 335i with the Braille 15 lb battery sitting for 2 weeks, 60% charge. The only way to get close to 100% charge is to charge it with a smart battery charger, then do your test.
I know this post is from 09, but I've seen it repeted a few times; CA should not draw when in sleep mode. Only things that need date and time like the radio should draw at all. I think the max draw should be around 20 milli amps.
