2017 AUDI A3 Fuelpropulsion System Problems

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...

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 (NHTSA 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...

The car started having issues around February 2024. The car first started misfiring and dying at stops which was a safety issue. When parked I noticed that there was an excessive amount of fuel that started coming out of the charcoal canister, another problem that could have resulted in the car catching on fire. The car could not be filled up with more fuel as there was pressurized fuel coming out through the fuel filler neck when the cap was removed. The problem was determined to be related to the currently active recall. I waited for 5 months for there to be a fix for the recall without being able to use the vehicle. I finally got tired of waiting and had my mechanic repair it. The fuel tank and charcoal canister were replaced and the old parts are available for inspection by interested authorities upon request. The car is...

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...

The high voltage battery no longer charges to full. Only 7 out of 8 possible indicator bars are illuminated, the car now only shows 17-20 miles available. When I purchased the car 3 years ago, it showed 28-29 miles available. Car was at Audi dealership, got tested, Audi says it's within tolerance. I disagree, 30% to 40% of the capacity is lost so far. There are many more owners that are reporting the same issue on the Facebook Audi A3 group.

2017 Audi A3 Etron Sportsback- Engine light turned on at 50k, when scanned for errors no codes. Then around 55k miles started to stall when slowing down or at a full stop. The car must be turned off then immediately go into drive. Felt very dangerous when driving in high traffic areas and areas with many stop lights/signs. Car error say Transmission Malfunction first then says something about Limited Power. We had changed ATF and filter, still had issues. Then it started to not allow to go into reverse. Issues were intermittently happening then became more constant. Finally towed to Audi dealer they are not 100% but they say a new transmission is needed. After seeing complaints of similar situation I think this should be a recall on the transmission for these cars.

Was trying to fill up my car at the gas station. The car would not accept any fuel. Frustrated, I went to try another gas station. Same thing happened. Went home to check and see what the problem was and gas started spewing out of the gas tank from where you fill it up with gas. Car (to my knowledge) has never been overfilled, by me. This is apparently a problem with the 2017 VW golf's as well (which run on the same platform as my Audi A3). It is a problem that most people are saying could be the Charcoal canister prematurely dying, or a suction pump dying, which is supposed to last the lifetime of the vehicle.

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...

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.

ENGINE STALLS WHILE ACCELERATING FROM A STOP. THIS CONDITION HAS BEEN DANGEROUS. CAR HAS BEEN TO THE AUDI DEALER 3 TIMES TO REMEDY THE PROBLEM. THAT CANNOT DIAGNOSE THE ISSUE. IT IS GOING IN FOR A 4TH TIME APRIL 12TH 2021. THIS ISSUE IS EXTREMELY DANGEROUS. THE CAR WILL LOSE POWER AND STALL AS YOU ARE PULLING OUT INTO TRAFFIC. HAPPENS DAILY.

2017 AUDI A3 SEDAN- WITH AROUND 47,000 MILES -STALLED OUT IN DRIVE THRU AND AT A RED LIGHT INTERSECTION. TWICE. ALMOST GOT IN 2 ACCIDENTS WHILE DRIVING ONCE ON THE HIGHWAY AND ONCE ON A CITY ROAD. ENGINE LIGHT ON DASH WAS BLINKING. CODE READER INITIALLY WAS READING P0300, P0301 AND P0302 .. MULTIPLE CYLINDER MISFIRES. TOWED CAR TO AUDI, AND THEY DID COMPLETE MAINTENANCE SERVICE. RAN CODES AND NOW ALL OF THE SUDDEN IT NEED A NEW TRANSMISSION AND THE CODE IS P0172 BANK 1 SYSTEM TOO RICH. I NOTICED THERE WAS A RECALL FOR THE THE ENGINE CONTROL UNIT (ECU) SOFTWARE AND WHICH CAN AFFECT AIR / FUEL MIXTURE WHICH MAKES ME THINK THAT THIS RECALL WAS PROBABLY THE CAUSE, BECAUSE PO172 CODE CAN BE DUE TO THE AIR/ FUEL MIXTURE GETTING TOO FAR FROM FACTORY SPECS. MY CAR HAS BEEN AT THE DEALERSHIP FOR 6 WEEKS, THE...

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...

MY CAR AFTER STARTING (WITH ENGINE EITHER COOL OR WARM) WILL STALL AT TIMES WHEN I'M GOING2-3 MPH. I HAVE STALLED AT INTERSECTIONS. I GO TO PUT MY FOOT ON THE GAS AND THE CAR WILL SPUTTER AND STALL. IT WILL THEN RESTART WITH A LITTLE DIFFICULTY THOUGH STARTS BACK UP. THERE ARE NO ICONS THAT ILLUMINATE ON THE DASHBOARD WITH ANY PROBLEM. THERE ARE NO CHECK ENGINE LIGHTS OR BATTERY LIGHTS THAT ARE GOING OFF.

WHEN DRIVING OFF AFTER STARTING THE VEHICLE, THE CAR STARTS JERKING AND 'KNOCKING' AND STALLS/TURNS OFF. THIS HAPPENS ALMOST EVERYDAY AS I REVERSE OUT OF MY DRIVE WAY AND DRIVE FORWARD. EXTREMELY UNSAFE! DOES NOT SHOW CHECK ENGINE LIGHT OR ANY OTHER LIGHTS.
