Any alternate service info to WIS?
Finding even the simplest information on WIS is an ordeal of going through submenus of duplicate information often in a viscous circle. For example, on my 2007 S550 I'm looking for the fog light diagnosis or wiring diagram. I understand a relay is involved but don't see if it's located in the SAM or the underhood fuse box. Spent over an hour on WIS with limited success. Would something like Alldata have more straight forward wiring diagrams and diagnostic procedures?

One can compare ease of use of WIS and EPC... about equal.
Unlike AllData, the WIS user interface requires skills to locate basic schematic like your fog light circuit.
