Hello everyone...i own an 2001 c class...battery died a week ago and replaced it... its been a week now and battery died again... when i jumped it a message came out and said "light sensor visit workshop"... i want to know if the problem is with the light sensor or battery....if anyone knows the solution to my problem or encountered this problem please post me back with some answers..... thank you...

 

I had this problem where my car would be dead every morning. I figured out that it was my electrical seats that caused the issue. I unplugged my seats (both passenger and driver) and my car hasn't died since. Eventually I will get the seats looked at when I can afford it.

 

thanks

 

I had this problem myself. My battery needed replacing as a result of dying many days in a row. However, the problem was a bad diode in my alternator. The alternator would charge the battery when running but would suck the power out when it was turned off. The light sensor message is not related to your problem but is one of the first systems that is shut off when a battery is dying.

 

thanks
