the seat control modules are running causing the dead battery. I have a 2001 C240 and had the same issue the module is located under the front seats, you need to unplug both cables under both front seats. this should stop the battery from dieing but you will not be able to move your seat unless you reconnect the cables.
I have a 2002 model doing the same thing.. Mercedes wanted $812.00 for the module. My problem is with the passenger front seat. There are four sets of wires and quick connects. Which is the seat control module?
