I also think my car had a couple battery drains on it from my exhaust controller and CTEK battery sense.
If anyone wants instructions.
It is pretty easy to do the replacement. undo the bracee held down with 13mm bolts. undo the negative post, 8mm. unplug all the cables on the battery distribution box that plug into it, you can leave the two other bolted on cables connected. undo the 13mm bolt holding the distribution box to the battery terminal post. move the distribution box out of the way, undo the 8mm on the positive post. remove the battery and replace. do all the steps in reverse order to connect it back up.

I just changed mine a few months ago but I used the factory battery from BMW parts local.The battery was 250 bucks and I registered it with the icarly app,
This was my problem was the exhaust controller for the Meistershaft exhaust ,I initially had it on the wrong fuse giving me battery drain, how I figured it out was when I installed the new battery I had to hook up the ground wire for the controller back on the bolt I used I noticed a spark when connecting, right there told me there was a load on the battery when the car was off, so Im pretty sure I swapped a perfectly good battery,You should relocate your fuse to a key switch on fuse with a piggy back fuse in the fuse block in the rear
