Fog lights come on automatically
I have a 2003 C320. I have had a battery drain issue and I have noticed that my fog lights come on when the car is turned off. The light selector switch is in the off position and not pulled out and no other lights come on. Just the fog lights. Any idea on how to fix this?

How long do they stay on? This is a feature to allow one to exit the garage at night. They should turn off after 20~30 seconds.
Battery drain issues on your MY are most often tied to seat modules that do not go to sleep. Unplug the modules located under the front seats, and see if the problem goes away.

If they truly are staying on and never coming off, there's probably a more serious problem than just the fogs. Front SAM, short in the wiring, ground issue, etc.
