Cigarette light stopped?
Mine did the same thing. The fuse is in the truck on the right side. Once you open it is a fuse on the right side on the fuse box.
It's a Mercedes. It's been engineered to save your life in every way it can. So, it won't light a cigarette! Outstanding!

Perhaps you are charging a device that draws too much current or the plug causes a short-circuit (I've seen even OEM cell phone chargers that cause this on some cars).
After noticing that a number of people are having the same problem, I decided to look in my trunk and see if the fuse was blown. I've attached a photo of the fuses that are in the trunk of my car.
The little yellow block of fuses on the right hand side is the "block of interest" to us.
It has room for seven (7) fuses in total. From bottom to top, they are numbered 67 thru 73 inclusive. And low and behold, there is no fuse at all in position #71 (the fifth from the bottom) - it's empty! I wonder if this is why so many people are having trouble with the 12 Volt Cigarette Lighter plug. In fact, I don't believe there is even a wire going to the back the panel for position #71 where the 15 amp fuse is listed.
Take a look at the photo and then take a look at your little yellow panel and let me know.
Update: Went out to the car tonight (2012-05-09) with a good LED Flashlight and a 15 AMP (Blue) fuse and pushed it into position #71 which I had conformed had a wire connected to the back of. The Cigarette lighter, also known as Socket, Front - now works. I don't believe that there was EVER a fuse in position 71. So, that problem is now closed!
