SL/R230: ESP switch does not disable traction
light up but when the car is running I don't get the light when pressing the ESP Switch.
Any way to check it?




The ESP light comes on if the battery is drained or disconnected. The wheel turning exercise resets the steering angle sensor, and turns the light off.
See if that works and let us know.
Try removing the button and opening it up, I often find broken pieces inside or dirty/corroded contacts. The switches on the center console are frequently subjected to spills and the fluid contamination ruins them easily.
