Please help! strong fuel odor located under the driver, passenger side. no faults reported when turning on the vehicle. fuel tank under vehicle shows evidence of fuel leak coming from the top. vehicle was purchased as brand new, i'm the first owner in 2013 straight from audi dealership. upon further investigation, after removing back passenger seat on the driver side, when removing round silver fuel cover, noticed some type of black tape or goo was melting above the fuel filter. hard to describe, see attached images. after turning the vehicle halfway on, not fully, i can see fuel leaking off the top, possible crack that was covered by black goo or tape. vehicle will run out of fuel 2-3 days after filling full tank.
Strong gasoline smell inside the passenger compartment and outside the car upon exiting. no leaks on ground. suspect cracked fuel pump flange
