What's wrong?

The fuel line on 2012-2014 Audi A6 and A7 vehicles carries gasoline from the tank area toward the engine. It has to stay sealed while the engine and drivetrain move, vibrate, and heat up during normal driving. On these vehicles, the line includes a compressed section that helped with installation.

That compression point is the weak spot. Audi traced the problem to manufacturing tolerance issues that leave that section less able to handle strain over time. As the vehicle is driven, vibration and movement around the line can weaken the compressed area until gasoline leaks from the hose. Audi later changed production to a redesigned fuel hose that does not use the same compressed section.

The warning sign is a fuel odor inside or around the vehicle. If occupants smell gasoline, that is the warning sign that the fuel line has begun to leak and the vehicle needs recall service.

Who's affected?

Both A6 and A7 are listed for 2012, 2013, and 2014, and each listing points to the same fuel system component.

The year and model narrow the match, but the VIN decides. Check your VIN to confirm whether your specific car is included.

What's the safety risk?

A fuel line leak releases fuel; near an ignition source, that raises fire risk. If occupants notice fuel odor, park safely and call an Audi dealer before another trip. Schedule the recall repair soon. Repair will be free at any franchised Audi dealer once available.

What should I do?

  1. Check your VIN to confirm your 2012-2014 Audi A6 or A7 is included in this recall.
  2. Wait for Audi's owner notice before scheduling if the remedy is not open in the dealer system.
  3. Contact a franchised Audi dealer and ask when the free fuel-line replacement that fixes the weakened compression point is available for your VIN.
  4. Reference recall number 17V781 and Audi recall 20AR when you call.
  5. Avoid ignition sources near the vehicle and stop driving if you notice a fuel leak before the repair.

What happens at the repair

At the dealer, an Audi technician replaces the fuel line that has a compression point tied to this recall. Because the remedy is listed as under development, do not treat this as a repair you can schedule until Audi confirms the campaign repair is open for your VIN. The dealer repair will be free once available. Audi offers a reimbursement program for this recall, so owners who already paid for a related fuel line repair should contact Audi customer service at 1-888-237-2834 and ask what documentation is required.
