What's wrong, in plain English

In some Audi A6, A7, S6, and S7 vehicles, the fuel level sensor in the tank may stick. This can cause the fuel gauge on the instrument cluster to show an inaccurate reading, so it may not reflect how much fuel is actually in the tank. Because the gauge can be wrong, a driver may run out of fuel without realizing it, which can cause the engine to stall while driving.

What you should do

1. Check your VIN at nhtsa.gov/recalls to see if your vehicle is affected.
2. Contact an Audi dealer to schedule the repair; you can also call Audi customer service at 1-800-253-2834.
3. The repair, installing a new fuel sensor, is free.

Where do I find my VIN, and what do I tell the dealer?
