X5 alternator bad?

Have you unlocked your cluster test mode? Test 7 or 9 will give you battery voltage.

Very convenient first step to check battery and charging system status without having to open the hood/trunk. Though if the battery indicator already lit up, dollars to donuts its the alternator in my experience.

Eyes light up...

Being a new BMW owner, I'm not familiar with this test routine. Are you able to point me to a resource?
