Thanks for the info. I just had my DCT shifter replaced on my 2013 M3 due to the low battery warnings I was getting. The battery was replaced by BMW just a few months ago and it had been on the tender for quite a while, so I knew it was more than just a flat battery. I'll keep my eye on the issue and recommend they look at the EDC module if it comes back.
