Headlights Cycling on and off automatically
After exactly 5 years of ownership today, my C350 with bi-xenons experienced the famous german electrical gremlins.
I came out of my parking garage in broad daylight, so the headlights were on from being inside. As I was pulling out, I thought my eyes were playing tricks on me when I saw the green headlight symbol in the instrument cluster cycle on and off (as well as the white glow of the instrument cluster). Of course, I was moving at the time so my attention was not on whether the headlights were on. I let it go, but tonight as I was turning the car off, the headlights instantly turned off as they should, but then the eyebrows and the interior lights started cycling on and off as well.
Great, so I am out of warranty and am about to go in for a service A. Cant wait to hear how much this will cost. I did find some similar cases, and people say the SAM needed to be updated, or a faulty light sensor.
Any updates on the situation from similar experiences would be really helpful

Saw a similar experience on this website in the past fortnight.https://mbworld.org/forums/c-class-w...sh-lights.html
Can you leave your headlights on 'manual off ' until the fault is found.?

Yeah last night my 08 when I was walking up to it the parking lights or the fogs did not turn on like they usualy did when you unlock the doors, could that be the light switch?

W204
The light switch seems to go out quite often. I just had my 2010 c300 light switch replaced at 40,000 miles. The passenger side parking lights, front and back would stay on even after I set the switch at 0. It drained my battery when I didn't drive the w204 for 4 days. Luckily, MB-roadside replaced the battery under warranty.
