The impact switch never moves, so theoretically it should never wear out. Some people have trouble with them but it's pretty rare. If you think it's giving you trouble, just jump around it temporarily and see if the problem goes away.
The EGR does give problems, and it needs replacement on a regular basis. Some go a long time without replacement but all of them give trouble eventually. It has a sensor on it that tends to wear out also. That will usually give you a trouble code when it fails.
