Can anything other than driving distances fix monitors so my car can pass smog?

What is your question?

I replaced car battery late in 2014. I had car repaired to fix erratic timing last month. Today car did not pass smog test. I had no fault indicator lights on the dash. Last repair was done et SAAB expert repair shop which now says to drive the car and (?) hope that it correct monitors. Last week end I drove the car for about 4 hours not knowing that I would fail test today.
