2017 Audi A3: gas smell in the cabin

Filed Feb 20, 2026 · Fuel system · WA

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.

In August 2025, my 2017 Audi A3 (VIN [XXX] ) experienced repeated stalling, strong gasoline odors inside the cabin, and a check engine light immediately after Audi completed recall-related service. The safety issue was later confirmed by the dealership to be caused by a failed suction jet pump (the federal safety agency Recall 24V110), which allowed fuel to enter the EVAP system and leak into the rear seat area and cabin. The leak was so severe that the rear seat and flooring had to be replaced due to fuel saturation. Before the problem was properly identified, I was repeatedly told the issue was “just the gas cap,” despite reporting fuel smell, rapid fuel loss after filling the tank, and the check engine light. During this time, I unknowingly drove a vehicle with a significant fire hazard. The cabin fumes caused physical symptoms and unsafe driving conditions. I was not notified of this recall at the time I purchased the vehicle in March 2022, nor was I notified of a second recall affecting the passenger occupant detection system (69BY), despite having purchased a one-year maintenance warranty. I only became aware of the recalls after experiencing the hazardous symptoms described above. The problem was confirmed and reproduced by the Audi dealership. Fuel odor, fuel loss, and warning lights first appeared within 24 hours after the initial service visit, and the safety defect was later linked to the recall-related component failure. This defect presented a serious risk of fire and exposure to gasoline fumes to both myself and other road users.

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.

Vehicle tank was almost empty. Was unable to fill the tank because the gas station pump stopped constantly without being full. Took 15 minutes to fill the tank. Fuel came out of my tank and a very unpleasant fuel odor came into the car. When arrived home gasoline came out of the tank again, a significant amount of fuel came out. Fortunately the car didn't catch fire. Took it to a mechanic and the gasoline pump valve was replaced. This valve is under the rear seats. No recall available for my car for this issue. I was told that VW/AUDI knows well about this issue but they didn't include all VIN numbers on this recall. I ended paying $140 for this repair.
