When checking the current drain through the 77 fuses on your W220, I would concentrate on the fuses that ALWAYS have battery power on one side (Circuit 30).
The other fuses require the ignition switch to be turned to get their 12 vdc. The relevant fuses are as follows:
f9, f13, f22 to f26, f35, f36, f39, f41, f42, f55, f56, f58, f61 to f74.
