Do the following to permanently turn off “Eco Start/Stop”
On the Multimedia System (Not the “Multifunction Display”) starting from Radio.
1. Push the control wheel up to bring up the menu, select “Vehicle”. using the wheel, Turning it clockwise then press on it.
2. Spin the wheel until you find “Dynamic Select” Press the wheel to select.
3. On the right had side use the wheel to select your preferred settings.
( I like the following:
Drive: Sport
Climate Control: Comfort
Eco Start/Stop: Off
Steering: Comfort
)
4. Exit and go back home (it saves automatically)
5. Using the “Dynamc” Switch, Select “Individual” you will find it before “Eco” or after “Sport+” (Mine is just after Sport+, Which is better because if you want to exit your “Individual” settings and switch to “Sport+” you only have to flick the switch down once, instead of going through all the options) You should see a little I* icon on your “Multifunction Display”.
Now every time you start your engine you no longer have to turn “Eco Start/Stop off by hand.
