I believe that my 2001 325i is experiencing a parasitic draw. I can't get the car to start after 3-5 days without use, and have replaced the battery/tested the alternator - both of which are good.
After letting the car enter sleep mode, I disconnected the negative cable from the battery and recorded a 2.60 amp draw. I began pulling fuses individually and found that fuse no. 49 and 52 both dropped the current draw to 0.28 amps.
Fuse No. 49 and 52 are involved with the Central Locking System (along with fuse no. 60), Interior Lights, and Windscreen Washer System (along with fuse no. 59). I've made sure that the interior trunk and glove compartment lights turn off when closed, so this is not the problem.
At this point I am stuck. What steps can I take to try to find and solve this issue? Any help will be greatly appreciated!

I'm having the same problem on a customers car but their car is only affected by fuse 49. I think what I'll do next is plug the fuse back in and now disconnect the controls to the windows, sunroof, overhead interior lights control, each one on the circuit individually to see if I can narrow down which one is the suspect.
Does the car have heated locks?
