Intelligent Battery sensor wire unplugged

So I bought my car a few months ago from a dealership. The other day I decided to scan the car for fault codes and it came up with 2E8D Intelligent Battery Sensor error. I looked at the battery and noticed that the blue plug that connect the IBS was unplugged. The car never gave me any check engine lights or anything and apparently from what I read this error won't give any lights. The battery looks like an OEM BMW battery. I'm just wondering why anyone would want to unplug this cable. Could it be so they wouldn't have to get a new battery registered?

IBS and shipping cable are not the same

I have heard the IBS can keep the car from starting if you have a low
battery. So if you have a low battery the trick is to disconnect it to start
the car. Also I think the car uses default values for battery charging when its
not hooked up.

Bringing this from the dead, what happens if we leave the IBS sensor unplugged? Will it have problem charging the battery or will it kill the battery?
