I would get the car checked out by Service. It was happening to the brand new 2006 S500 we got. These days, auto manufacturers love to have modular computers in the vehicles. Especially MB, in S class there are 7 or 8 separate computers controlling each function groups. i.e. computer for lighting system, computer for brake systems, etc.
Now, when you shut off the car, and if one or two of these computers do not go to "sleep mode", it will drain the battery. In our case, it was draining it overnight.
MB Service re-flashed all possible computers with the latest software and now they are working just fine.
I suggest you taking the car to them and tell them to check all the computers to see if they shut down properly.
Let us know how it works out....
