Module isn't shutting off? help solve my battery problem

[killcrap]

yes, i would start pulling fuses at the front and rear panels.

What have u installed on your vehicle such as led lights? The final stage resistor is most likely the prob.

Nothing, I don't have anything plugged in, no phone charger, dice, nothing.
My fan isn't blowing so how could the fsr be the problem?

Final stage resistor will kill the battery a lot quicker than a week. Only takes a few hours.

Did some research and this is from Steve at Morristown BMW

If your Shifter light is on, the car is definitely staying awake.
Your Battery will go down within days. If the light is not on
you can have a parasitic draw, while the car is in sleep mode.
The only difference, is the second draw is from a module
witch can’t wake the system (not mission critical), and it will
take a lot longer to discharge the battery.
If you want I can give you a procedure to narrow down the fault.
But you will need a good voltage meter (Fluke 83).

OK I'm having electrical demons in mine. I've got the battery replaced, alternator rebuilt, charges fine when it runs, but it seems like it dies after 3 days.

My mechanic cannot figure out, and he's tested everything and even fully charged the battery. He has also replaced the battery to make sure.

Any ideas? I would really appreciate it.

If the mechanic is not equipped to check parasitic draw and/or isn't familiar with the BMW systems and way of shutting down in stages etc. you may need to find a different/better mechanic.

In the other thread you mentioned you're driving a 4.6is... How would they be able to rebuild the alternator???? It is a water cooled alternator that has a completely sealed and non serviceable solid epoxy front. If they claim to have rebuilt the alternator I'd seriously question that as it is an impossibility.

UPDATE!

So, after hours upon hours trying to figure out why my car keeps on dying we did not solve the issue but atleast narrowed it down to where the dirty gremlin might be.

While doing a draw test, my mech started pulling fuses in the glovebox. Turns out fuse #61 is the issue, the fan module 50amp. Immediately the reading dropped from dropped from 21 to 2. So, I mentioned this forum and the Final Stage Resistor inferring that it might be related however, we are not too sure about where this fuse exactly relates! Anyways, turns out we pop the hood and unplug the FSR just to see what happens with air conditioning on full blast. Well, the fan was intermittently budging clockwise and sometimes twitching counterclockwise but that's it! We pulled that fuse out, and the auxiliary fan didn't move. So the FSR is for the fan outside. We came to the conclusion that the draw is coming from that circuit that fuse is on. Please excuse my terms, I am in no way technically inclined and am trying my best to translate to you guys about what happened. Nevertheless, I pulled out the fuse #61 and the auxillary fan modulator (the plug that allows the fan to have different speeds) before I went to bed and the P light still remains on when I checked this morning. I did that to see if it was related in anyways and it doesn't look like it. Any further input would be highly appreciated. I hope this is not a problem with the ECU...

Do you have DSP? My stupid ass mechanic took out my dsp amp becuase the battery kept dying. He said "the battery was dying so we replaced the battery. When it died again, we figured it was the amp becuase it was making a noise and the radio was crackly." No that he doesn't have the car anymore, I will check the above as well. If he got that wrong too, I can't wat to have my attorney write him a letter.
