Default Battery is draining

Hello,
Recently with my 530xi the alternator went out and the battery was flat. So i got a new alternator and took the battery to autozone witch told me the battery was still good. after putting in the new alternator and charging the battery it went flat in a few days again. could it be a wiring problem? trying to get fixed soon so any advice would be great.

What brand alternator did you buy? You only want to put an OEM in not an off brand. Also make sure you did not damage the cable on the battery if you took it out

Its the IBS sensor.
Take out the blue wire from the battery, issue will go away.
