Was the no start issue when the starter and engine were warm or cold?
You should see a 12.6 VDC battery voltage. Anything less is a fail for the BMW battery.
BMW starters usually fail when they get a rotor to stator contact swelling which happens when the engine is warm or hot.
If your start condition was cold then it might be battery time.
You can take the cover off the back in the trunk where the battery is and measure there but usually the jump post in the engine bay area is accurate...
