2014 Audi S4 Fuel System Problems

I HAVE ENCOUNTERED THE PROBLEM OF AIR BUBBLE FORMATION IN MY FUEL SYSTEM (CODE 16903) WHEN READING CODES IN MY CAR. I THOUGHT IT WAS JUST A FUEL PUMP ISSUE SO I REPLACED IT. I THEN REALIZED IT WASN'T JUST A PUMP ISSUE AS THE CAR KEPT READING THOSE CODES AND KEPT STOPPING. I TALKED TO A LOCAL AUDI DEALERSHIP AND SAID I WOULD HAVE TO GET THE FUEL PUMP VAPOR EXTENSION. WHEN ASKED THEY SAID THAT IT'S ONLY A TSB NOT A RECALL DUE TO IT NOT BEING A SAFETY ISSUE. NOW YOU TELL ME, MY CAR WENT INTO LIMP MODE AND STOPPED ONCE IN THE MIDDLE OF THE HIGHWAY, AND 3 TIMES IN THE MIDDLE OF TRAFFIC 2 WEEKS LATER. I BELIEVE IT'S A SAFETY PROBLEM AS ANYONE COULD'VE RAN INTO ME AND CAUSED BIGGER PROBLEMS. I DON'T THINK I SHOULD PAY 800 DOLLARS FOR MY SAFETY. THAT PIECE SHOULD'VE BEEN INCLUDED IN THE FUEL PUMP ASSEMBLY FROM THE BEGINNING. FROM MY PERSPECTIVE AND THE EVENTS THAT UNFOLDED, THIS IS A SAFETY PROBLEM AND MY CAR NEEDS TO BE FIXED ACCORDINGLY.

AFTER 2 ENGINE OIL LEAKS, IN 2.5 YEARS, I SMELLED GAS FUMES IN THE CABIN NUMEROUS TIMES, SCHEDULED AN APPT FOR A CHECK WITH THE WEST ISLIP NY AUDI DEALERSHIP. PICKED UP CAR FROM DEALERSHIP, WITH WORK ORDER AND SERVICE REP. SIMPLY STATING "NO PROBLEM FOUND" UNDER EACH OF MY 5 CONCERNS, WHICH TOLD ME THAT THEY DID NOT EVEN LOOK AT THE ISSUES. WITH EVERY WORK ORDER, WHICH ARE NUMEROUS ON THIS CAR, IT IS STATED WHAT WAS DONE, BUT NOT THIS "SERVICE". TWO DAYS AFTER PICKING UP MY VEHICLE, AUDI REPORTED A RECALL DUE TO GAS LEAKS IN THEIR VEHICLES. MY VEHICLE IS STILL UNDER LEASE AND WARRANTY, YET THIS DEALERSHIP TOOK IT UPON THEMSELVES TO IGNORE MY CONCERNS, WHICH COULD POTENTIALLY BE FATAL.? ABSOLUTELY NO INTEGRITY, AND LACKING ANY SENSE OF MORALS.
