Would anyone have a pinout diagram for the ecu on a 2008 s550 (w221)? I'm trying to rule out shorted wires while addressing some codes for valve solenoids, vent valve open circuits. Etc. Can't seem to find one online and the one in wis only shows 4 pin numbers per connector. Here's a pic of the ecu with the mb and bosch part numbers.
