How to search the EPC?
 

I would appreciate it very much if someone here could show me how to navigate the the EPC to reference a certain MB part number to all the vehicles that use(d) it.

Or, is that not possible!?

i dont know, but depending on the part, there is possibly an aftermarket option.
Big set of books (i mean, huge) called HOLLANDER INTERCHANGE MANUALS.
for the most part, it'll be larger mechanical components listed instead of, say,
window switch or seat belt, etc. it excels when you're looking for parts such as
radiators, driveline, gas tank, valve cover, headlight, etc.

large libraries may have it so check your area. I found this expensive set of books
in Bellevue WA last month and camped out there to copy interchangeable parts
for my car (99 E320)

Hit the "F11" key & a window will open.

If you see a box with a flashing A, just type in the part number & hit enter.

If you don't see that box, click on "part without vehicle data" & that box will open.

IF you are trying to find a DIN number like 000000-000000, you need to backspace the A & type in a "N" first.
