Open the full vehicle complaint log (all categories)BUZZING NOISE IN BACK OF CAR TURNED OUT TO BE FAULTY FUEL PUMP. AFTER SEVERAL DAYS IN SHOP THE SERVICE REP TOLD ME THAT THERE WAS ANOTHER PROBLEM -- A "BURNT" OR "CORRODED" WIRE NEAR THE FUEL PUMP AND FUEL TANK THAT COULD BE A "SAFETY ISSUE." THAT WAS 3 DAYS AGO. STILL NO UPDATE FROM THE DEALERSHIP. I AM WONDERING IF OTHERS HAVE HAD PROBLEMS WITH THE FUEL PUMP ON THE AUDI S4. I'M PARTICULARLY WORRIED BECAUSE EXPOSED WIRES NEAR A FUEL TANK SOUNDS LIKE A SERIOUS SAFETY ISSUE.
