1999 Mercedes Benz CLK430 headlamp defective warning

Hi there,

Thank you for the donation,

You can do a visual inspection of all lamps and get some one to check your brake lights as well as the eye level light, if all lights are working, I would be expecting that there is a fault in the sensor that monitors this function, for this I would suggest that you contact your dealer for assistance as I feel that it will be a control module somewhere in the system that has failed, start here.
