celluloidheros - thanks for providing the detailed updates and a final resolution, glad to hear your issue is finally resolved. i've been following the thread in hopes of resolving a similar issue.

I suspect I have a drain caused by something similar to your #63 (intermittent), but I haven't been able to catch it drawing current after the car is in sleep mode yet. You mentioned that you saw (in sleep mode) .62A in some early posts, but 10-30 mA (in sleep mode) in later posts. were you ever able to 'recreate' the higher current draw situation, or was it random and you happened to catch it by chance?

I have a good battery (~12.6V resting), functioning alternator (~14.1V while car is running), 13mA current draw while in sleep mode. But I still have a dead battery if leave the car sitting for a few 2-3 days.

Dont mean to reopen this thread but Ive started one of my own recently due to my battery drain.
Ive replaced the FSR as I thought that was the issue before since I had issues with the AC coming on after I started the car with a jump (turned it off before turning off car).
That didnt help.
What is happening to me is that my car comes out of sleep mode randomly. I have an SMG so I hear the pump prime as if Ive opened the door or trunk or unlocked the car. I suspect that may be enough to drain the battery after 24 hours of sitting or so.
Any inputs on this?
I would like to find what is causing the car to wake up on its own.

Thanks,

Greg

Well since you say it's like you've opened the door or trunk I suggest you start there. Make sure the sensors for the door and trunk are not falsely detecting that they have been opened. It may be easier to just replace rather than diagnose.

i had the same issue, but that resolved when i started turning the light knob from automatic to off when the car was not on. no more problems with drained battery dont know why it works, but it does for me atleast

Im gonna start looking at those, in the meantime I was hoping someone had a list or something showing what switches made the car wake.

My Ride: E46 M3
E46 M3 Parasitic draw.

Hi, my 2001 E46 M3 has had a power drain since purchase. Upon inspection fuses 62 and 63 show draw of 8v and 3.5v respectively after the engine is switched off, if I pull and refit the fuses the power returns to zero.
Does this sound familiar to anyone or does anyone have any clues?
Do these circuits share a common earth and if so where is the terminal for these please?

Slight amendment... apparently I only have to pull and refit fuse number 63 to reset the system to zero volts...
