D3 digital speedo change to kph
I have changed digital speedo on the DIS from mph to kph for driving on continent by changing coding for region in instrument cluster but it's always just a temporary change. If I cycle ignition it is back to mph. The coding is saved and fuel usage stays in l/100km but the digital speedo always switches back to mph next time ignition is turned on.
Does anyone know how to make a permanent switch until I want to change it again as it is a bit of inconvenience to change the coding every time.
