octavia 2016 doesn't show state of charge, does anybody know what is the reason?

I checked and it is the original one, tomorrow I'll test it with vcds and see if it was properly coded 🙄

     As an update the only thing not matching through vcds Is the battery serial number witch is 1111111 but I learn that doesn't really matter. Reading the voltage with the engine off is 12.3V and on is 13.3V , all of this after one hour driving😒.I think either the battery is going bad or alternator not charging properly, but still doesn't explain why it can't see the soc value

Do you have a Stop/Start battery system?

Is it the original battery?

 

If you have a Stop/Start battery then having no SOC figure is normal.

 

This is because the battery is not charged fully by design and is also allowed the fall to less than 50% before the 'Smart Charging' system kicks in.

If the car showed the SOC most people would think that their battery was no good.

 

12.3 volts at rest and 13.3 volts ( if ) when it is charging is low for a Stop/ Start battery system?

     The car has stop start so I presume that the battery should be . I did some different measurements using a multimeter directly to battery and this are the results: 12.6v ( engine off, ignition off), 10.somethingV when starting the engine and 14.4 V with the engine on. So battery is good , alternator is good. Vcds can't be used in my opinion for exact measurements of the battery, at least not as better than a multimeter. 
   If that's so with start stop then I am not worried anymore 👍

Take a picture of the battery label. Someone will tell you if it's the right spec.

AGM = Absorbant Glass Mat which is a Stop/start type battery.

Looks original.
