What's wrong?
The fuel line on 2013-2014 Audi S6 and S7 vehicles with 4.0L engines carries gasoline from the fuel system toward the engine. It has to seal tightly while the engine is running, because fuel moves through the line under pressure. A sound line keeps gasoline contained and away from hot engine parts.
On affected Audi vehicles, manufacturing tolerance issues left the fuel line outside the intended fit range. That means the line does not seal the way it should. As the engine runs and fuel pressure builds, gasoline can leak from the line instead of staying inside the fuel system.
There is no warning sign before failure. The first sign can be fuel already leaking, so a fuel smell, visible wetness near the engine area, or smoke needs immediate attention before the vehicle is driven farther.

What happens at the repair
At the dealer, an Audi technician replaces the fuel line covered by recall 13V450. The owner notice timing was listed as late October 2013, but this section has no current remedy status, so treat the dealer repair as free once the recall repair is open for your VIN. The work is aimed at stopping the fuel leak described in the filing. Parts and labor are covered under the recall.
