There are many posts about ECO mode and how it works or doesn't so I thought I'd post the conditions to be met for it to work:

Conditions for the automatic engine stop:
  • The ECO start/stop function is activated.
  • The outside temperature and atmospheric air pressure is within the range that is suitable for the system.
  • The engine is at normal operating temperature.
  • No engine diagnosis is active.
  • The engine speed is within the range that is suitable for the system.
  • The automatic transmission fluid temperature is within the range that is suitable for the system.
  • The temperature in the vehicle interior is within the set range.
  • The fuel tank is sufficiently filled.
  • The system detects that the windscreen is not misted up when the air conditioning system is switched on.
  • The charge level and the voltage of the battery are sufficient.
  • The battery temperature is within the range that is suitable for the system.
  • The engine bonnet is closed.
  • DSR is not activated.
  • AIR BODY CONTROL does not raise the level.
Conditions for the automatic engine start:
  • The vehicle starts moving.
  • The brake system requires a running engine.
  • The temperature in the vehicle interior deviates from the set range.
  • The system detects moisture on the windscreen when the air conditioning system is switched on.
  • The battery's charge level is too low.
