The alternator is unserviceable which doesn't keep the charging system going.When the battery is fully charged the vech will run and drive for a while until it drains the charge down in the battery because it isn't being replaced by the alternator......Hope this helps.

and?

The foil where the bulb socket connects goes bad. They make a retrofit socket replacement solution. You will have to tap into the #6 wire (labeled on socket) for the drivers side and the #1 wire for the passenger side. Mercedes has a bulletin on this but refused to recall as of 2/1/2011. The parts at Mercedes are about $23.00 each side. Easy fix.

You should be able to do this easilly on your own.

just to give you an idea, it is this way

The answer is in the owners manual. If you don't have one the service department at the local Mercedes Dealer will probably show you for free...it only take a moment to do.

I just took my car to the dealer this morning. They changed the bulbs for free and it is working fine! take your car to the dealer unless it is out of warranty?
