Hi there, got an issue with the ESP button that does nothing. It is a 2013 i30 GD 1.6 CRDI 110 bhp.Tried holding it for longer and it did not work, pressing does nothing either. When I turn the ignition on, the ESP light and ESP off light will light up on the instrument cluster, then disappear which is right. However, with the engine on, when I try to turn it off it just will not work. Also it goes wheelspinning in the wet as if it did not work at all. The light on the switch illuminates blue when I turn the lights on which kind of makes me think the button should work but it does not. Also, next to it is a little piece representing driver/passengers' seatbelt warning lights which does not work at all and it should blink red after I have turned the ignition on for 6 seconds and then disappear for those seats which are either not occupied or have the seatbelt fastened. Does anybody seem to know what could be the culprit? Thanks in advance.
