What is the voltage on your display?
When I select the voltage reading mode, I get the next values...
After cold start, charging voltage shows around 14.3
Than slowely drops....
After driving for about 30 minutes the display shows around 13,5v
Only lights, radio and climatecontrl on....
What does your display show?
Thanks

1. Insert key into ignition, switch to position “1“.
2. Press buttons or repeatedly until the mileage is displayed within the Multifunction display.
3. Press cluster illumination button (1) 3 times in short succession. The battery voltage will be displayed.

It drops to 10 or 11 when I crank it and slowly drops to 13.8 or so after driving for a bit. I am not sure what number is too low though. My guess is you're fine at 13.5, but I am not 100% sure.

If your battery is older or weak, a drop while cranking to 10v is possible , but if it dips anywhere below that to 9 or 8, I'd look into getting the battery tested and make sure its the right rating for the car.
