2007 BMW 323i, no start, no crank, electronic's still work

cailmcdonald · 02-12-2020, 11:42 AM

I live in Alberta, Canada and about a week ago in -40 weather i got my car to start then wrote an exam. Around 3 hours later I came back and my car wouldn't even crank yet all my interior electronics worked fine. I brought it into my garage in hopes it was too cold to start but nothing. Already tried disconnecting IBS sensor and change DME relay. Any ideas?

The basics first .
Measure the battery voltage and put a slow full charge on
it.
