2008 Audi A3 ELECTRICAL SYSTEM,FUEL/PROPULSION SYSTEM

THE CHECK ENGINE LIGHT ILLUMINATED AND HAS NOT BEEN ABLE TO PROPERLY DIAGNOSE. MORE THAN ONE MECHANIC HAS TOLD ME THE CODE P0171 THAT READS AS THE DIAGNOSTIC DOES NOT CORRELATE WITH MY CAR AS MY CAR DOES NOT HAVE A PCV VALVE. THEY HAVE INSPECTED THE CAR TO LOOK FOR SIMILAR ISSUES AND HAVE FOUND NONE. YET THE CHECK ENGINE LIGHT REMAINS ILLUMINATED. THERE WAS A RECALL REPORTED 09/30/2009 ON MY TYPE OF CAR UNDER CAMPAIGN 09V377000 BUT MY VIN IS NOT SHOWING AS AFFECTED BY THAT CAMPAIGN EVEN THOUGH THE CODE THAT IS COMING UP IS A SIMILAR ISSUE. I AM EXTREMELY CONCERNED ABOUT THE SAFETY OF DRIVING MY CAR NOW. I CAN'T NOT REPAIR WHAT I CAN NOT DIAGNOSE. I BELIEVE THAT I AM AFFECTED BY THE RECALL.
