Battery disconnected for a 1 with malfunction that will not clear. on 2003 Mercedes-Benz E500

I had my car stored for a while I served my country. Now I cannot get the one malfunction code to clear. My seat use to move back when I would turn the car off to get out of it and now the seat remain still. If I press code 2 for my child it would move to his seating arrangement. How can I seat this back up and at times it humms like it wants to work?

Your best bet will be to seek a MB dealer or shop that works with MB vehicles. A scan of the trouble codes will reveal the issue with the seat and the memory problems. It sounds as if one of the motors have failed relating the memory functions and/or switch.
