Replace hose from EGR Valve on 2004 Ford Modeo (III) TDCI (130)?

My car judders between 1950 and 2050 rpm. Searching the net it looks like this may be a simple issue to resolve.

Apparently, this could be a split hose from the EGR valve. Does anyone have any guidelines on how to replace this or even an annotated diagram of the engine so that I could check whether this is the potential issue?
