Comand online/Engine data - Display not working properly

[Cherrypd]

On our new to us 2016 CLS Sporting brake 220, the engine data display doesn't accurately show the power or torque being used. Actually whilst normal driving when you lift or feather the throttle iss displays what you are using. However when you apply power it stays at zero. It's almost as if the readings are reversed to throttle input. Enginee oil temp and battery voltage are fine.

We've also noticed that the ECO stop/start never kicks in and the dash display stays yellow.

Any thoughts please or seen it before.

The only thing I can suggest to take the car to an MB specialist who has genuine STAR, scan for fault codes, and crucially, update the software on all relevant ECUs.

Regarding start/stop, it's most likely due to a weak starter battery, or (less likely) a faulty auxiliary battery.
