A non-serviceable, faulty rollover valve inside the gas tank is causing the vehicle to leak fuel (also fails to contain fuel in the event of a rollover - exacerbating fire hazards in the event of an accident). The solution is to tear apart the entire bottom of the car to replace the entire gas tank. A $6,000 repair according to the Audi dealership - two local shops quoted $4,000. There are no warning messages. Discovered when I exited the vehicle to strong smell of gasoline as maybe a gallon had spilled outside the vehicle. Dealership was aware of the issue.

Defect investigations
Fuel Leak due to Suction Jet Pump Failure within Fuel Tank (Remedy Effectiveness of Recall 16V647)
On December 12, 2023, the Office of Defects Investigations (ODI) opened RQ23-007 to investigate the remedy repair effectiveness and scope of Volkswagen (VW) recall 16V‑647. Recall 16V‑647 was issued on September 2, 2016, for a defective suction jet pump (SJP) inside the fuel tank. Failure of the SJP could lead to a fuel leak from the vehicle. This recall covered certain model year (MY) 2015-2016 Volkswagen Golf and Audi A3 passenger car vehicles. The recall remedy repair replaced SJP Version 1.0 with an improved version, Version 1.1. The SJP is designed to purge fuel from the evaporative emissions (EVAP) system. VW’s recall filing stated the SJP may have been damaged during assembly, which could potentially allow fuel to flow directly into the EVAP system. Over time, the fuel could accumulate in, and cause a leak from, the charcoal canister filter element. ODI received consumer complaints of SJP failure leading to a fuel leak, refueling spit back, refueling shutoff, and/or fuel odor in vehicles previously repaired under recall 16V‑647. Additional complaints alleging SJP failure leading to the previously stated outcomes were received in vehicles outside the scope of recall 16V‑647, including MY 2016-2020 VW Golf and Audi A3 vehicles. VW issued recall 24V‑110 on February 14, 2024, to address issues with SJPs Versions 1.0 and 1.1. The recall remedy replaces the SJP Version 1.0 or 1.1 with an improved version, Version 2.0. Recall 24V‑110 covers certain MY 2015-2020 VW Golf (including Golf GTI), 2015-2020 Audi A3, and 2019-2020 VW Jetta GLI vehicles, including vehicle previously repaired under 16V‑647. Vehicle owners were notified of this recall in April 2024 and VW’s projected date for owner notification of recall remedy availability is August 2024. In view of the recall being conducted by VW, ODI is closing this Recall Query (RQ). The Agency reserves the right to take additional action if warranted by future circumstances.

What 2015 Audi S3 owners say
Most recent owner complaints, unedited.
I am reporting a Safety Remedy Denial by Audi of America (Case #[XXX]) regarding a failed suction jet pump and charcoal canister in my 2015 Audi S3. This failure resulted in a fuel leak and strong fuel odor near the exhaust, creating an immediate fire hazard. Although Audi issued a 15-year/150,000-mile warranty extension ([XXX]) for the 8V chassis A3 population, they are denying coverage for my S3 variant. This is in direct contradiction to Audi's own TSB 2068171/5, which explicitly states the A3 model group 'includes S and RS versions.' The dealership (Audi Rancho Mirage, RO# [XXX]) confirmed the failure of the suction jet pump (Version 1.0/1.1) but refused the safety repair at no cost because the 'U49 Warranty Key' was not in their digital system. This component is part of the federal safety agency Recall 24V‑110 and Investigation RQ23007. Audi is failing to honor federal safety protections for the S3 variant of the 8V chassis. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Gas pump shuts off and stops pumping fuel into my car with a loud hissing noise before it shuts down the pump. I can not properly fill my vehicle with gas. This is not a single incident it is an ongoing problem.
Unable to refuel car. Gas pump keeps clicking off and fuel backs up spilling out of fuel port. Mechanic tested fuel system and reported fuel tank has faulty jet pump seal. Mechanic says a recall was effected for certain audi models with this issue due emissions dangers and fire risk.
Tail lights stopped working, the wire harness in the vehicle is known to get sheared due to a pinch point at the trunk hinge, this pinch point over a period of time will result in damage to the wire harness that controls the rear taillights as well as the opening and closing functions of the trunk. This is a known issue, with a TSB having been release, replacement is only offered if the damage is noticed during warranty period. This damage is hidden behind the trunk lining and can go unseen until the damage is done.
Gear Shift Micro Switch This is a documented issue recalled for VW and Audi vehicles between 2015-2019. VW recalled all and still is fixing the issue in cars from those years, yet AUDI decided to just offer an extended warranty to those cars for that specific issue. Who is responsible VW or AUDI. If Audi is owned by VW and the issue is in both types of cars made by them, why aren't AUDI vehicles included to the recall and repair.
When driving, without AND more importantly, WITH, a passenger in the front passenger seat, the Passenger Occupant Detection System (PODS) light goes on and indicates that the passenger air bag has been deactivated. I looked on line and saw that Audi has already recalled certain 2015-2019 Audi A3 Sedans but apparently my car is not part of the initial recall. I think the recall is BIGGER than Audi estimated and that my car should also be part of the recall. I plan to take to Audi to repair.
While pumping gas, a strong odor is always present. While pumping gas the pump will stop multiple times before being filled in it's entirety, I can't hold depress gas pump handle I have to slowly fill car with gas or risk spilling fuel.
The EVAP suction pump stopped working resulting in refueling issues. Fuel accumulates in the EVAP system and spills outside the vehicle
I have had a passenger airbag recall since 2021, and I have tried to schedule the maintenance for that recall several times, but each of the 5 times that I’ve tried, the Audi dealership (in Glenwood Springs, CO) says they don’t have the parts in stock. Each time that happens, I’m told I’ve been put on the list for the next parts shipment. I am so tired of waiting, while in the meantime, my passengers are considered unsafe in this vehicle. I need to have this repaired soon, please. Thank you.
