a little help for my father in law please

Hi all ,

My father in law has a 130i on a 55 plate

Has asked me to have a look at his car because every now and then the battery symbol comes up on the dash.

The car is fitted with a genuine bmw battery and has the “health indicator” on the top

Green = healthy and charging
Black = not charging
Yellow = replace battery

The battery is the original one from new and is showing green so I though it could be the alternator giving out slowly so I tested the batter with a volt meter with the car running and it was fluttering between 13 and 14 volts which shows the battery is charging
Does anyone have any ideas as to what is causing the battery light to come on its happened 4 times in the last month

kind regards owen
