Hello All,

new to the forums and have a quick question. I have a 2012 S 350 diesel, after not starting the vehicle for 3 full days. my battery is completely drained. I can't even unlock the vehicle. I have gone to the local dealership and they are absolutely useless and clueless. They replaced the battery, starter (i dont know why and multiple times) and the issue isn't going away. They tried to tell me that the rad fan stay on which drains the battery and expect me to believe that. When the fan is on, it is loud and clear where i hung out around the car for hours when parked in my garage and no fan kicks in and or stays on. Has anybody ever run into a similar issue where they can relate? it feels like there is a loose wire somewhere that is not maybe grounded and or a sensor that might potentially be on to monitor something, i dont know lol..please help
