EGR module will not reset after battery change 6 months ago?

I tried to get car smogged but EGR module hasn't reset. Drove 200 miles, same result. Drove 30o miles, freeway and stop and go, same result. I took the car to Hyundai dealer they refused to help, wouldn't even do a diagnostic because I was wanting repairs in order to get the car smogged and they aren't smog certified. Finally took the car to a smog test and repair garage. They have a Dynamometer and have run through the drive cycle daily for a week plus additional driving on the street and after a week it still has not reset. They are going to try for 1 more week but if they can't get the unit to reset so they can smog test, is my only option then to junk this car? I'm just sick about having to junk this car with so few miles but in California I don't know what else I can do.
