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.
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.
