What's wrong, in plain English

Some Audi vehicles are missing a small sealing pin in the connector for the engine's control computer. Without that pin, moisture can get into the connector, and moisture inside the connector can cause the control computer to malfunction. If the control computer malfunctions, the engine may stall while you are driving. Dealers will check the connector for the missing pin and for corrosion, and fix it if needed.

What you should do

1. Check your VIN at nhtsa.gov/recalls to confirm your vehicle is included.
2. Contact an Audi dealer to schedule the repair (Audi customer service: 1-800-253-2834).
3. The repair is free of charge.

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