It started with my DME going bad, replaced it along with the alarm. Then the mechanics concluded the MPM was bad. Replaced it along with the wiring. After it being there over the weekend, it's still dying. I have been without a car for 2 weeks and it hasnt worked properly in over a month at this point I'm stuck and ready to take it somewhere else. But my question is what could possibly be causing the draw? Is it simply a process of elimination? Checking fuses and modules? Any help is appreciated

 

i just had the battery and SZL replaced for this issue.
They said the SZL was not letting the car sleep.
This car is too complex!!

 

I tell you one thing, according BMW of Sterling; it's very easy on 5 series to find what is causing a draw. They told me almost 99% of the time they can tell a problem. Well I can believe them because they fixed my car.

I guess they have proper equipment

 

Have they checked the battery?

 

Smh wow how did they come to that conclusion tho?

Smh they're making it hard

Battery was new but it's done now

 

With my experience I would assume the MPM but your situation may be different. You can start by getting a meter and measuring things. I've discussed this on the board a few times.

 

has it got the updated sealed IBS lead?

 

Im gonna do this tomorrow when I take the car home, should the car be on when I test the fuses?

 

Not 100% sure how would I know if it did or didnt?
