AdBlue Level Coding

[tecnomatic]

I want to make coding for a B-Class W247 car, so that the AdBlue level is always displayed at the fuel level. Can someone write the code?

I think this would only be possible if such a feature was already available in the head unit software (i.e. the programs that show information on the car's displays). Then it could be coded (i.e. the configuration and bits adjusted so that it would be displayed). However, if this feature is not already available in the car's software, I doubt that anyone has deep enough access to add such additional software code to the car's software.
