How to check the battery voltage on a BMW 3 Series car

Model: BMW Serie 3 E91, E90, E92 - Years 2005-2013
Part: Battery

In this video we see how to check the battery voltage on a BMW 3 Series E91 version car: first we insert the key and turn on the ignition. We press the button/wheel located at the bottom right of the speedometer; we hold it down for a few moments until some messages appear on the display, then we start pressing it quickly until the screen 19 (the number at the top) with the message "lock on" appears. We press again quickly until we reach the serial number 22 which will display an alphabetical code. From here we go to screen 9 and see the voltage in the display, which in this case is 12.3 Volts.
