What's wrong?

The fuel supply line on the 2013-2015 Audi A8 and S8 feeds gasoline to the high pressure fuel pump. That pump raises fuel pressure for the engine's injection system, so the line has to stay sealed while fuel moves under pressure near hot engine parts.

On affected Audi vehicles, that fuel line can become porous from the inside as it ages. Audi reported that the exact root cause and outside factors were still under investigation, but field parts showed the line breaking down internally. Once the line becomes porous or damaged, gasoline can leak instead of staying contained in the fuel system.

The warning sign is a fuel smell inside or around the vehicle. If occupants notice that smell, the fuel line has already started leaking or letting fuel vapor escape.

Who's affected?
