2009 Audi Q5 Engine Problems

ON 7/02/09 MY AUDI Q5 (VIN# [XXX]) WAS PURCHASED FROM, AND SERVICED BY BARRIER AUDI BELLEVUE, WASHINGTON; NOW DOING BUSINESS AS AUDI BELLEVUE A DEALERSHIP OWNED AND OPERATED BY AUTO NATION. TECHNICAL SERVICE BULLETINS [TSB] WERE SENT TO SOME AUDI OWNERS ON 12/6/2013 CONCERNING REPAIR AND CLEANING OF THE SECONDARY AIR CONTROL VALVE WITH A WARRANTY EXTENDING THROUGH 07/02/2019. THIS PROBLEM WAS INITIALLY CORRECTED ON 12/27/2013 @44,445 MILES, MY LAST SERVICE WITH BARRIER WAS 09/13/2018 AND AT NO TIME HAD I RECEIVED NOTICE THAT THE PROBLEM COULD RESURFACE. THE TSB PROVIDES : "THE SECONDARY AIR SYSTEM ON THESE VEHICLES IS USED TO HEAT UP THE CATALYTIC CONVERTERS QUICKLY DURING COLD-START CONDITIONS?. OVER TIME, AND DEPENDING ON DRIVING STYLES, CARBON WILL BUILD UP IN THESE SMALL 10MM PORTS AND CAUSE FAULTS IN THE ENGINE CONTROL MODULE FOR SECONDARY AIR, BANK1/BANK2 INSUFFICIENT FLOW? SOME MODELS DO HAVE A WARRANTY EXTENSION, WHICH COVERS THE SECONDARY AIR PORT CLEANING UP TO 10 YEAR/110,000 MILES. PLEASE CHECK WITH YOUR LOCAL DEALER FOR DETAILS. KEEP IN MIND, IF ANY OF THE CONTROL VALVES, COMBI VALVES, OR SUPPLY LINES ARE DAMAGED, OR FAULTY, THOSE ITEMS ARE NOT COVERED UNDER THE WARRANTY EXTENSION, AND WOULD HAVE TO BE REPLACED BEFORE THE PORT CLEANING CAN BE PERFORMED." ON 10/01/ 2019, AN ENGINE WARNING LIGHT WAS DETECTED ON THE Q5 WITH APPROXIMATELY 106,000 MILES ON THE ODOMETER. ON 10/28/2019 A CLAIM [#190822437]` WAS FILED WITH AUDI USA AND DENIED AS UNTIMELY FILED. AUDI BELLEVUE CARRIED OUT REPAIRS AT MY EXPENSE FOR $ 2045.75. GIVEN THE FACT THAT THERE WAS NO NOTICE, THE CONTINUED WARRANTY PERIOD SHOULD BE EXTENDED BY AUDI USA AND THE COSTS OF REPAIR REIMBURSED. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
