RECALL CAMPAIGN 20YF; DESCRIPTION- SUCTION JET PUMP I was not made aware of the recall until fuel began gushing out of my passenger side rear. The Audi dealership was aware of the recall in July of 2025 when I had routine maintenance at the service department, however it was not addressed. Fast forward to the fuel leak in April 2026, I was informed by the repair reps that the leak was due to a failed charcoal canister. I attempted several times to notify my advisor and manager that the recall addresses that the suction pump defect can cause fuel to flow into the EVAP system causing leaks through the charcoal canister. I was told that this was impossible and repair costs would not be waived. I also reached out to the Audi consumer line and was told that only the dealership could have fees waived even though the representative agreed that my issue was due to the failed suction pump.

While driving at highway speeds, a warning light appeared as well as an alert indicating the car was limited to no more than 4000rpm. After coming to a stop, a strong smell of gasoline was noticed in the passenger compartment. Continued driving home uneventfully but the strong smell of gas persisted. The next day I drove the car to a mechanic. Their inspection notes the following: The technician verified the customer concern of a fuel smell. He performed a fault scan, finding codes for low fuel pressure. He inspected the vehicle, finding a major fuel leak under the intake manifold, most likely from a cracked fuel rail. The system is supposed to operate at 125 bar of fuel pressure, but is currently at 9-11 bar. The high pressure fuel pump is operating at 100% duty cycle, which means it has overheated and been damaged. Metal shavings from the fuel pump then ends up inside of the injectors, ruining them. The low pressure fuel pump may be ok, but it is unclear at this time. **RECOMMEND REPLACING FUEL RAIL, HIGH PRESSURE FUEL PUMP, INJECTORS WITH SEALS, AND PRESSURE SENSOR **MAY NEED LOW PRESSURE FUEL PUMP They also noted that the leaking fuel could cause a fire hazard. The fact that this fuel leak happened at only 98,750 miles and that the car continued to be drivable with fuel spraying all over the engine compartment is extremely concerning.

The vehicle cabin started to smell like gas and the car would not accept fuel into the tank. Took to Audi/VW independent repair shop where they indicated fuel jet pump in gas tank was not working properly and that it had flooded various components with fuel (charcoal cannister, etc.). Directed us not to drive as it was a fire danger and said that we should send to Audi to see if they would cover this under warranty as it was a major emissions and safety problem. Towed to Audi dealer in Dallas. Dallas Audi dealer indicated this sounded like exactly what had happened for a recall issued for 2016 A3s. I learned this was subject to a warranty extension. Am working with the dealer who is trying to determine if that applies. Regardless, this is my daughter's car and a fuel leak with fumes in the cabin is a danger that should be fixed by recall.

On Tuesday, June 7, 2022 my vehicle began having a hard time accelerating, then my vehicle started leaking out gas from the back of the vehicle located in front of the rear passenger tire. I then took the vehicle to Audi West Houston to have a diagnosis. After a day and a half, Audi misdiagnosed my vehicle with ethanal composition too high and recommended that the gas tank be drain. I then took my car to an independent mechanic who replaced the fuel pump. On the way to the independent mechanic for a second opinion, the check engine light surface. I then stopped at the gas station to put gas in the vehicle, but the vehicle would not take fuel even though After the fuel pump repair, the car was still misfiring and gas was still leaking from the rear of the vehicle and gas fumes would be smelled from inside the car. The charcoal canister of the vehicle was changed with OEM parts. The vehicle's sending units were pulled and the fuel level was tested. The vehicle's Leak Defection Pump was then inspected for the fuel intrusion and were not obstructed. The vehicle again began leaking fuel. The purge and vent valves of the vehicle were working properly and the vent filter was wet with fuel. The fuel was being pushed into the charcoal canister from an internal valving issue inside the fuel tank. The independent mechanic then called an authorized Audi dealership who acknowledged similar problems in Audi vehicles. The authorized Audi dealership deemed the car unsafe to drive and suggested that the independent mechanic park the vehicle outside of the mechanic shop because a simply spark could cause the vehicle to easily caught on fire. Audi also acknowledged that there are no available parts for the car as all of them are on indefinitely on backorder. The car is not only an emission issue but also a safety issue with not feasible solution. Furthermore, I live in Texas during an unpredictable drought, even the weather could cause the vehicle to spontaneously combust in flames.

I was refilling my fuel tank of my vehicle at gas station, but it kept clicking off with the back pressure as if the tank was full. I tried filling slowly to see if that would work, it did the same thing. . I left and on my way on the highway, a young man signaled me to pull over, I was hesitant, but did so. He showed me that fuel was draining from my car. Luckily , I did not have a fire as it was close to the muffler system. I got it to a nearby mechanic shop to see what was the problem it was not a burst hose nor a tank leak , however they first thought it was the siphon hose that was blocked , it was not. They traced the fuel leak to the evap system and found that the charcoal canister was filled with fuel. And the car still would not take any fuel because back pressure, kept forcing the fuel out. Upon seeing that they advised me to take the car to the audi dealer in coral spring florida. I did so and told them of the problem and asked if there was a recall on this problem. They said no. I pointed out to them that the 2016 audi a3 has a recall that is exactly as what is happening to my car. Recall # 16v647000 this was issued between september and october of 2016. They said that they would diagnose my car for $390.00 I ok"d that. This is their diagnosis: 1 fuel tank = s2654.00 plus tax/ss I am not in agreement with that and called to audi america and made my complaint, the young lady " morgan " took my complaint and made arrangements to call the dealership re their assessment and call me back. She called me with no real answers except to say that I have a right to a second opinion.
