Smart 451 start/stop

[Simone]

Hi everyone, I have a smart 451 mhd 71cv year 2010.
I would like to know if it is possible to deactivate the stop/start system permanently with a software change.

Thank you.

Hi,There is no permanent way to disable it as of yet.
You can program “Favorite” button (diamond icon) on the left side of the steering wheel to toggle the start system stop on and off.
Go to Settings / Gear Icon>Apps>Diamond Button>Short Press>Other>Auto Start/Stop

Thanks Cozmo for your reply.
But I don't have any buttons on my steering wheel.
I think this is only possible on some models subsequent to mine or with optional equipment that I don't have.
I will therefore always have to manually disengage the stop/start.

Hi Simone,
I have read on another forum that it is possible to disable Start/Stop on the 451 via software, (unfortunately the thread stopped with 'Solved').
The little information available states that the setting is protected by a seedkey so Vediamo or DTS used for change, my best guess would be to look at the ECU or RSG parameters.
On the 453 I think this setting can be changed using DDT4ALL.

Regards.
