something is draining battery..4 hours and battery dead..i checked fuses on front SAM module friday and little water go on front fuse box..from drain hole..do you guys suggest take out front SAM module and check? relays and fuses is good.

I ordered front and rear sam units..do you guys think I should start with front first? Please look pictures ..its raining and water dripping on front sam unit..is it normal in Mercedes w212 for drain water?

car is working now..i first replace rear sam same problem car cant start ..then i remove front sam unit. found and replace 2 capacitors was damaged.. dry unit with hair dryer.
put front sam back and problem solved with few faults.. rear right door not open and sometimes front wipers not working. possibly more faults inside front sam..bacause its dificult open,desolder front sam..only i replaced capacitor..which i have access.

I often have this problem when starting. Pressing the Command on/off switch for 10 seconds resets the system. A nuisance but not a real problem.
