Oh! Just don’t turn the alarm on! In fact, your car will likely lock itself after like thirty minutes of f you don’t turn on the alarm.

I tried

disconnected negative> 10A on multimeter > Reading was 1.63> removed fuse 153 > reading 0.03 > took off multimeter > connected multimeter again just to make sure > reading above 1 again

153 fuse is for interior lights, started car interior lights were still on, not sure.

What do you do when you park it ?

I just park my car in her spot outside my townhouse. Sorry for the delayed reply, I'm working on this this afternoon. Any progress?

EDIT: I just realized maybe I didn't answer your question. I've been using a CTek BMW-branded car charger the day before I absolutely need my car.


Today, I tried to track down the parasitic draw. I found that the parasitic draw is between 1.68 amps and 1.74 amps. I pulled fuses 101–141, as well as 146, 147, and 154. Nothing reduced the draw.

Something strange was happening after about 15 minutes of pulling fuses—it's like the car came to life again and started drawing 6 to 9 amps. Does that ever happen with yours jdhillon656?
