How do you know if your erg valve or erg vacuum modulator valve needs replacing?
It's almost impossible to tell just from how engine is working. Unless you have hesitation, car lacks power and efficiency is low. And of course if you have EGR error code(s). In order to test EGR you need to have a small vacuum hand pump. Then you need to apply vacuum to the EGR system and see how it responses. Also, sometime EGR valve just needs to be cleaned. For the you need to remove the valve and check on presence of carbon deposits. Also if the valve itself cannot be moved freely, it might have to be replaced. The hoses around EGR system have to be checked on cracks, and replaced if cracks are present. EGR vacuum switching valve usually does not break. But EGR valve get very dirty time to time and has to be cleaned or replaced.
