The indicator on the panel is on, but the headlights do not shine The lamp has burned out or the contacts have oxidized Replace the lamp, clean the contacts. WD-40
Fogheads flash or burn dimly Poor contact in the connector or low voltage Check the mass on the body, clean the contacts
The rear fog lights don't turn off. Relay stuck or button faulty Replace the relay. J344 steering-button

If after checking all the elements, the problem remains, it may be defective. light control unit (J519). In this case, a computer diagnosis (for example, through the VCDS or ODB2 scanner).
