Hello,

I have an issue with my 2008 bmw 750 li. The car cranks but not start. It will start pretty fast when I jump it with my jump starter but if I drive around and then shut it off, it dies again. I downloaded and used INPA to pull some codes which I have provided below. My best guess is a bad battery even though my current battery tests good at the auto parts store. I also thought possibly a bad door handle or the ibs (if its equipped with one). Any help would be greatly appreciated. Thanks

I am thinking you might have a bad alternator or voltage regulartor. 

The other thing I wanted to ask is if you registered the battery when it was replaced.

    The battery should have a sticker on the side or top. Can you see what date that is. Typically it will be something like 07/15

    Bad battery most likely.

    Yes I did. It turns out that the battery was running at 26CCA so it was extremely bad. A new battery fixed the issue. Thanks all for the help!
