Need a better description of the diagnostic fault code. There' more than one related to the EGR valve, but fault codes never say to replace parts. They only indicate the circuit or system that needs further diagnosis. A vacuum leak should not cause an EGR code unless possibly if the leak is in the hose going TO that valve.
