My battery has a draining issue as well. If there is no uncommon drain to your car, what should the multimeter read? I don't think it will read zero. So, what is the normal reading with no uncommon drain?

0-15 mA (0.000-0.015A) - This is a normal reading. If the battery is having problems, check the age and state of charge. It may be time to replace this battery simply from age or normal wear and tear.

16-24 mA (0.016-0.024A) - This is outside the normal range, but is not excessive. Check to see that all security and remote starter power and ground connections are functioning properly. Ensure the battery is charging properly and has a good state of charge.

Over 25 mA (>0.025A) - This is beyond what is considered acceptable. Start pulling fuses or disconnecting power of aftermarket accessories to see if the drain goes away. If still present after this, proceed to pulling OEM fuses. This method is the most effective way of determining the offending excess current drain. Once located, repair the problem and re-check.

Disconnect the ground cable from the battery and then connect an auto-ranging DMM set for current measurement between the battery negative post and the ground cable. With the car off and the doors & trunk closed the current draw should be 30-60ma. If more than that, pull one fuse at a time to find the offending circuit.. If you can't eliminate the excessive current draw by pulling fuses, start looking for improperly installed aftermarket electronics. If you fine one or more fuses that affect the current draw, trouble shoot that circuit(s) using the information from http://wedophones.com/BMWManualsLead.htm. Mine was the aftermarket amp, which clicked when I touched the negative cable to complete the circuit. Make sure you actually unplug your amp to see if your draw is effected.

Might also help to take your battery to get it tested at O'Reillys, NAPA, etc.

Oh, yours was an aftermarket amp? That makes me less sure if its my amp as my whole system is completely oem :(
