SEAT CONTROLLER MODULES, THEY CONSTANTLY DRAIN THE BATTERY WHEN THE CAR IS OFF. THIS IS A VERY VERY COMMON PROBLEM WITH MERCEDES C CLASS. THE CONTROLLER DRAINS THE CAR BATTERY TO THE POINT WERE THE CAR CANNOT START, AND CONTINUES TO DO THIS IF THE CAR IS NOT DRIVEN EVERYDAY. OBVIOUSLY HAVING A CAR BATTERY GET SUCKED BELOW 3V IS NOT HEALTHY FOR THE BATTERY, AND IN THE END EVERYONE WITH THIS PROBLEM HAS TO REPLACE THEIR BATTERY MANY MANY TIMES. *TR
