In DAS Developer mode :

In the menu that shows , you scroll down untill you read the line : Tankinfo im Reichweitebild
enable this option

if you watch your Instrument Cluster , you notice that scrolling through the menu , nothing changed .
For this , the "Koiinstrument" needs a reboot.
to do this in Developer mode we go back by hitting F1 -> 3 times
then choose Ansteuerungen -> Gesamstliste aller Ansteuerungen ->
Scroll down untill you see the line : Steuergeraet Resetten (PowerON-Modus) (FN_Reset_SG_Power_ON)
