The contact owns a 2018 Audi Q7. The contact stated that there was an abnormal fuel odor inside the cabin of the vehicle at start-up, and the MMI System warning light remained illuminated. The vehicle was taken to a local dealer, where the vehicle was diagnosed, and the contact was informed that the fuel pump was faulty and needed to be replaced. The vehicle was repaired; however, the MMI System was not fixed. The manufacturer was notified of the failure. The approximate failure mileage was 93,000.
Fuel pump failed and is leaking on my 2018 Audi Q7. Audi has confirmed it will need to be replaced at my cost. Audi also confirmed it has an extended warranty to replace the faulty fuel pump on other model years on the same q7 vehicle model, for 150,000 miles. It appears that to rectify the issue, the same part is replaced as on the warranty fix. Why was model year 2018 not included in the warranty if it is the same part?
DRIVING ON INTERSTATE 29 AND SUV STARTED ACTING FUNNY AND THEN STOPPED. CALLED AUDI CARE AND THEY HAD TRUCK TOWED TO OMAHA NE. THEY PUT IN NEW FUEL TANK, PUMP AND LINE. HAD MY SUV IN SHOP FOR TWO WEEKS LESS THAN TWO WEEKS LATER DRIVING AND ALL THE SUDDEN MY GAS LIGHT COMES ON. I STOPPED AND PUT GAS IN AND GOT HOME. DROVE INTO THE GARAGE AND FUEL WAS RUNNING OUT FROM UNDER THE TRUCK. CALLED AUDI CARE AGAIN AND COULDN'T GET TOWED UNTIL FUEL STOPPED LEAKING BECAUSE OF SAFETY CONCERNS. TRUCK HAS BEEN IN SHOP FOR OVER TWO WEEKS AGAIN. SO, OUT OF OVER 6 WEEKS I HAVE HAD MY Q7 FOR LESS THAN TWO WEEKS TO DRIVE.
