Official summary
Audi: fuel gauge does not reflect fuel tank is full. The fuel gauge does not show full even though the tank is completely filled. This may occur after the vehicle has been transported by a vehicle transport truck. The lowered reading is triggered when the vehicles are loaded onto vehicle transport trucks or when parking on an incline. The vehicle is tilted, causing the fuel level sensor value to change without there being a speed signal in the instrument cluster. As a result, the instrument cluster perceives a refueling process. *pe

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
