having a few problems with my smart 453
the steering wheel buttons dont work and also ESP traction control light comes on saying inoperative .
Can someone please help.
Thanks in advance
I don't know this for certain but, based on the info it could be that the clock spring is having an issue. This makes sense only because the 2 system that you mention are only related by proximity and the clock spring having an issue could explain both items acting up.
Ideally you would want to take it to a shop that has a scanner that can communicate with the ESP module to see what code(s) are stored and are the reason the ESP light is illuminated. That is much better than my internet guess.
Let us know if you go that route and what you find.
