Recently i have had my ESP light come on. It seems to come on and go off when it wants to. I get a sharp but light cough or like a jab on the brake before it come on. Tunring the ESP on/off makes no difference. I've cleaned all wheel sensors. I read the codes and get a warning window with the text "too many communication errors" warning when using the ABS channel. Anybody experience these problems, and know of any solutions.
