Details
Golf 8 Digital Cockpit: the last number on the speedometer scale. Only the display layout changes, speed and limiters do not. Unit 17 on the Golf 8 protects this object with SFD — a token for unit 17 is required. The map has not been tested by writing to a Golf 8. Odyx reads the object first and shows the changes. Undo from the write history.
Other options
This is one option of the “Speedometer scale” setting: only one can be active.
