Some CEL's will reset after a certain number (3, most often) of key on - key off cycles. I don't know if the EGR one will. Otherwise, as mentioned, see a local parts store's code reader will do it. Assuming, of course, that the EGR was the issue to begin with. CEL's get us into the right area, but they don't always tell us what exactly is wrong.

Or disconnect battery and see if it reappears.

Although then hen you have to reset certain modules.
