W204 battery charge voltage reading in speedo cluster ?

[vijilants]

Yesterday I called out Mobilo because I had a flat battery on my W204.

The engineer that came out jump started it and then was monitoring the voltage values via an engineering menu in the car, but it was being displayed in the centre circle of the speedo.

Does anyone know how to access this in order to display these values ?

Thanks

Not sure if this works on all w204 but this method works for facelift models with 12 button steering wheel option.
Key to pos 1.
Scroll main display to odometer screen with outside temp.
On steering wheel press & hold the phone answer & OK buttons for 3 sec.
New menu appears with 3 options top one is Vehicle data.
Ok this option. It will then display Voltage & Amps.
