is there a way to fully turn off esp, i know it turns off but im guessing when your having a bit of fun drifting on track it will turn on again

 

Try dyno mode.
Key in on position,
Temperature screen,
hit reset button 3 times.
tune dynomometer on.

Beware EVERYTHING is disabled. You don''t even get anti-lock brakes then

 

Does DynoMode also disable the airbags?

 

Don't know, try it and let me know.

 

I tried to do this in my w211 e500 and it didn't work... when your on the temperature screen, put the key in 1st position, or 2nd position? or do you mean turn it on completely? Sorry if I sound dumb I'm just not clear on it I hope you help, thanks
