This was a 2013 Mini R57. While performing a parasitic draw test with your multimeter, you need to let it sit for an hour after you begin, so all the modules can go to sleep.
From my experience, normal draw will start at 4.5 amps, than go down to 375ma, than 250ma, and finally approx. 10-20ma.
In this case, the vehicle would not get below 125ma. Determined fuse 49 was the source, which only powers the factory stereo amplifier. Found water damage on circuit board. Used amp fixed the problem.
was useful to me! i just diagnosed the same problem. 120mA - fuse 49.
Do you know if the amplifier is really needed to get some radio working? I'm tempted to live without putting back a fuse in.
Glad to hear the video helped you. Unfortunately you will have no sound whatsoever without the amplifier. I remember not having it plugged in, and causing that. If you clever with electrical work, you could probably bypass the amp, but if you disconnect it or remove power, I believe you will have no sound whatsoever.
Does it matter if the car is locked/unlocked or if you have a door open?
Seems like you would need to lock it to let those modules enter sleep but you need access to the car's interior for the fuses, or will waiting for an hour let the modules go to sleep regardless?
Yes you definitely need the doors closed in order for everything to shut off. Windows can be down though. I carefully climbed in through the window to get access to the fuse panel to narrow down where the draw was coming from. You could also wait inside the car and have the multimeter on the window. And to be clear, car can remain unlocked.
@@tadsworkshop thanks for the quick reply! About to try this on my R55 which is showing CC-ID 415 "increased battery discharge"
@@shaunflynn7301 cool, I hope you get it figured out! I was just thinking about this, but maybe instead of closing the passenger door, just close the door latch with a screwdriver. That will make the car think it’s closed. When you are ready to close that door, squeeze the door handle and pop that latch before you do so.
Waaay better than crawling through that window, lol,
