2016 AUDI A6 Fuel/propulsion System Problems

I own a 2016 Audi A6 3.0T. After filling the fuel tank completely, the vehicle only traveled approximately 190–200 miles before the fuel gauge indicated empty. This represents a sudden and significant loss of fuel range compared to normal operation. There are no warning lights, check engine lights, fuel smells, visible leaks, rough idle, or abnormal noises. The vehicle operates normally otherwise. The issue appears to involve excessive fuel consumption or incorrect fuel management without any driver warning. This condition poses a potential safety risk because the vehicle may unexpectedly run out of fuel while driving, which could result in loss of power in traffic or on highways, increasing the risk of an accident. The issue has been observed repeatedly after refueling. At the time of this report, the vehicle has not yet been inspected by a dealer or independent repair facility, but diagnostic evaluation is planned. Based on owner research and symptoms, the issue may be related to a fuel system, engine management, or emissions-related component malfunction that does not trigger a warning indicator. No prior warning messages or lamps were displayed before or during the occurrence.

I’ve stated to dealer I’ve been having ongoing problems with my vehicle and they failed to fix the issue , while refueling the fuel nozzle stops and fuel spills. They said it’s safe to drive it’s just a sensor that needs to be moved

1. Vehicle airbag indicator has illumated. I haven't received a recall letter from manufacturer. Have concerns about driving with airbag light on. 2. There is a recall for electrical wiring. 3. Fuel system/ fuel rail is being recalled.

AUDI RECALLED 2012-2015 A6 CARS WITH THE 2.0L TFSI ENGINE, ALONG WITH OTHER AUDI MODELS, DUE TO FAULTY COOLANT/WATER PUMP (NHTSA RECALL # 18V-229 MFG RECALL #19N3/19N4). FOR THE A6, THE BRACKETING WAS FOR CARS BUILT FROM 4/4/2011 - 12/22/2014. THE BRACKETING FOR OTHER MODELS IMPACTED BY THE RECALLED VARIED FROM 2012-2017. MY A6 2.0 WAS BUILT IN FEB 2015, BUT WAS CLASSIFIED AS A 2016 MODEL. ON 8/28/2019 MY CHECK ENGINE LIGHT TURNED ON. I TOOK THE CAR INTO MY AUDI DEALERSHIP FOR SERVICING. THE TECHNICIAN STATED THAT I HAD A DEFECTIVE COOLANT/WATER PUMP, AND THAT THE PUMP WAS ABOUT TO BURST AND NEEDED IMMEDIATE REPLACEMENT. I WAS AWARE OF THE RECALL, AND ASKED IF THE PUMP ON MY CAR WAS SIMILAR TO THE PUMPS COVERED UNDER THE RECALL, WHICH THEY CONFIRMED THE PUMP PART NUMBER ON MY CAR MATCHED THE PUMP PART NUMBER THAT WAS BEING RECALLED. HOWEVER, SINCE MY CAR WAS CLASSIFIED AS A 2016, IT WAS NOT COVERED UNDER THE RECALL. IT APPEARS THAT THE BRACKETING THAT WAS USED TO DETERMINE WHICH CARS SHOULD BE COVERED UNDER THE RECALL WAS NOT BROAD ENOUGH FOR THE A6 MODELS, AS IT APPEARS THAT THE DEFECTIVE PUMPS WERE ALSO USED ON SOME 2016 A6 MODELS OR CARS BUILT AFTER 12/22/2014.
