2002 w220 s430 the vehicles battery will intermitantly be dead after sitting for two-three days. this usually happens once a week. I will have no problem the first time I leave the car for a few days drive it for two days and it may or may not be dead after sitting for anoither 2-3 days. There is never more tan a 40ma draw on te battery when tested. The battery has been replaced. I have retrived codes for safety time out for the central locking system (all doors and trunk) I yesterday I unplugged the central locking pump and did find and remove a nav disc now waiting to see if te problem happens again. Any other thougts out there
