Car turned off while driving ~ Electrical issue?

F13.KENN · 02-12-2019, 12:15 AM

Not my car, but my moms (2012 528i base model). I wasnt with her but she was driving down the road about 30 mins from our house and said the car turned off while driving and it wouldnt start back up. Went to go help and it wouldnt start at all or even crank over. still had power but it would kinda go out and come back every now and then. Had jumper cables and couldnt jump the car. Ended up having to get it towed to our house. Bought a new battery and coded it in and still wont work.

I scanned the codes and i wrote them all down.. wrote down 2 and a half pages of codes. 80% of them were something electrical related like "DSC high undervoltage", or something about the drivers door, mirror, or a headlight.

Hopefully someone can help out. Thanks!

Check all the fuses?

You don't give enough information.
There are a number of situations the car will shut down for protection.
More where it goes into limp mode for the same reasons.
If it is beyond your ability( No offense), you should have it checked professionally.
If you don't want to go to a dealership you can find an Indy starting here.
