i have a 05 w211 e55 amg SBC was damaged due to accident, just replaced it with another used one. while trying to bleed the brakes with DAS i get an Note " Voltage at control unit SBC:0.2V" . what does that mean ? im i connecting the battery charger at the wrong place ? i connected the charger in the trunk, positive on the battery and negative to the body of the car.

from what i understand it is the aux battery in the front that powers the SBC system.

what r u using to bleed the brakes? if you using a pressure bleeder you can unplug sbc which put sbc in default with valves open and bleed

SBC units are also VIN coded for each car. So, I don't believe a used unit will turn on in a car with a different VIN.
