2010 E350 Traction Control Won't Turn Off
 

I have a 2010 E350 and I've tried to turn the traction control off by using the button above the radio, but had no luck. I've tried it from having the car on, to having it started. I also tried pushing it and holding it down but still no luck. Anyone have any suggestions?

If it won't turn off then either the switch is malfunctioning or you have an issue with the ESC. Get onto a wet surface and see if you can light up the ESC dash warning.

I did it going for smog few months ago and from memory, I disable it with wheel buttons.
Technician at smog stations could not find it.
But mine is 2014 model and I don't have dedicated radio, nor any button above.

^ Yes, the newer models require you to go through the MF Display to disable ESP. The older ESC is accessed by the button he is referring to near the Comand.

Yeah I've got the light to pop up before when going kinda fast over a speed bump. Upon pressing the button though, my light does not pop up.

General rule with ESP problems is to start with making sure all tires have the same rpm aka diameter.

same for me not sure what’s it is it keeps coming on and off on my 2010 e350 but if you hold the button above the Radio for about 6sec then turn car off take out the key open the door close the door started it back up it should go away
