Light señor drive to workshop message
 

I have mercedes C 230, model 2005, A warning appeared saying " light sensor drive to workshop " I have noticed this warning for four months and it appears every two days and the light flickers and feel the power of the car became weaker. What could be the problem?i already replaced the battery, what is the malfunction? Can any body advise me what is the problem? and what i need to do to get rid of this message.
thanks.

My guess is it's the light sensor.

Tommy lol

OP
have you checked your battery voltages when car is off, key on, engine on, at higher rev, when the issue happens?
If not get us those results.
Which light flickers?
Sadly on the w203 and all modern cars a lot of things can cause issues and the only way to do proper diagnostics is with the manufactures own diagnostic computer (star in this case)

Ok, it sounds funny, but I'm being serious. It's probably the light sensor for the headlights, and that's why it keeps coming on, since he hasn't replaced the sensor.

Thanks for your feedback. i already checked the battery voltage by expert and every thing is ok. The light of the dash board start flicking for a few seconds then the radio and window power will cut for 2 seconds then the warring message appear. if i the start the car again the message will disappear and the car back to normal!
