Hello all,

I have a 2013 328i and recently got the "Charging Malfunction" warning regarding my battery. I was luckily able to make it home but now I can't drive 20 yards without having to jump the battery and then it dying again. Im thinking it's a bad alternator. I'm at 109k miles and thinking it's time to be replaced. However I saw a post about a bad RCS module could be causing the issue as well. The battery is fairly newer so I don't think thats the issue but could be wrong. In regards to changing the alternator is it easy to do myself? I am handy with tools and normally do my own car maintenance however I am a newer BMW owner and don't know much about the cars. Any insight on this battery issue would be greatly appreciated.

You should have one of these to constantly monitor both the battery and the alternator condition. Never fix anything that isn't broken. https://www.amazon.com/gp/product/B0...e?ie=UTF8&th=1
