Has anyone resolved a a0c1 code before?

Hey guys, I am new to the forum and figured I should ask the community first before I spend any more money. I have a 2011 135i DCT that wont start and is giving me a code;

00a0c1 CAS: Engine Start, Starter operation

When you try and turn the vehicle on, it sounds like the starter wants to engage and you hear a humming noise for about 1-2 seconds and then nothing.

I tried replacing the fuel pump and the starter as I previously had a long 3-4 second crank. But after the car would not start, neither the new fuel pump or starter seemed to help the no start issue.

This is my first BMW and i've only had the car for a month so I am wondering if I may be missing something. Any input would be greatly appreciated.
