You will need a cable to connect from the car to a computer.
People usually recommend this one.

But I bought mine from Amazon and works the same.
You then need to download and install BMW Tools, you can find them on the same site.

After you install the software and connect to the car you may need to tinker with the COM ports through device manager so the software can talk to the car's modules, I said may because I didn't have to change anything mine worked out the box.
After you connect the car to the computer insert the key and push start without actually starting the car, launch INPA and make sure it says you're connected and that it shows ignition ON.
After you see it's communicating close INPA and Launch NCS-Expert then follow these steps.
Now the next part isn't gonna make sense unless you're familiar with the software so go through all the steps and watche the video, after you know how it works you need to change these values...

That's what I did with my 2010 328i, I know there are probably easier ways of doing it but I have seen so many posts were people try different things until they make it work. The above steps worked for me and it took me about an hour to get the hang of it and I'm damn near illiterate.
After enabling the halos as DRL I also enabled digital speedo, close windows and sunroof with the fob (this wasn't an option on my car) and set the dash lights to always on.
