W204 Headlights - always on even when it is not dark

Hello to everyone.

Model: W204 2013 CDI 220

I have recently been experiencing a problem with headlights in AUTO mode.

Ordinarily, they switch on automatically when it starts getting dark, however for some reason they are now permanently on, even during the day in bright sunlight.

As a result, the daylights are off.

I can switch the headlights off if I turn the dial to off, however when I switch it to AUTO, they are back on, even during the day.

Is this something that can be fixed easily by cleaning a sensor, etc. or does it require technical expertise?

Thank you.

Some models have "daytime running lights" feature that you can disable in the Vehicle settings.

Many thanks for your reply.

However, my problem is not with daytime lights, but with the main headlight.

Under normal conditions, during the day, I have daytime lights (LED) on and headlight off. This is normal and expected operation. Then, as soon as it starts to get dark, the headlight automatically switches on.

What is happening now is that the headlight switches on even during the day, and the daytime lights (LED) are off. In other words, it is the opposite behavior: the vehicle switches the lighting system on as though it is dark all day.

The sensor is probably faulty. I believe the sensor is in the center of the windshield at the top. Make sure this isn't really dirty in front of that area where your rearview mirror hangs.

I wondered where it was. I noticed when I drive into the sunset the lights are off. Turning away from the setting sun makes them turn on.

Thanks for the tip.

Is it the sensor in the upper middle part of the windscreen, or is it somewhere on the dashboard please?

I have a 2009 C300...in the settings you can set the HEADLIGHTS to always on when the car is running.
It can also be turned off in the same place.

This is true for the 2008-2010 cars, but starting in 2011 the cars got LED DRL and there was no setting to run headlights all the time as there was in the past.
