I've been through the archives and have found bits and pieces of information with respects to the various electronic control systems on a W210.

Is there a site or could we start a thread that would give a BASIC overview of the electronic control systems?

I often see abbreviations that I do not understand, and even when I do figure out what the abbreviation stands for, I do not know what that particular electronic control unit is responsible for or does.

Thanks for any and all replies!
