What an Audi VIN tells you
An Audi VIN is a 17-character code that identifies your specific vehicle. Each position in the VIN reveals something different: the manufacturer, the model, the year it was built, the factory where it was assembled, and a unique serial number. Reading an Audi VIN takes practice, but once you know which positions to look at, you can pull basic facts about the car without needing a dealer or a VIN decoder tool.
The VIN appears on your registration, insurance documents, and the dashboard at the base of the windshield on the driver's side. You can also find it on the driver's side door jamb and on the engine block itself.
Key Takeaways
- Positions 1–3 identify Audi as the manufacturer; position 1 is always "W" for Audi vehicles built in Germany.
- Positions 4–8 describe the model, body style, engine type, and safety features specific to your Audi.
- Position 9 is a check digit used to verify the VIN is valid and has not been altered.
- Position 10 shows the model year, using a letter code that repeats every 30 years (A = 2010, B = 2011, and so on).
- Positions 11–17 identify the factory, transmission type, and the unique serial number of your vehicle.
Positions 1–3: World Manufacturer Identifier (WMI)
The first three characters identify the manufacturer and the country where the vehicle was built. For Audi, position 1 is always W, which means the car was manufactured in Germany. Position 2 is A, and position 3 is U, together spelling out the Audi manufacturer code.
If you see a VIN that starts with something other than "WAU," the vehicle is not an Audi, or the VIN has been tampered with. Some Audi vehicles built in other countries (such as Hungary or China) may have different first characters, but the vast majority of Audis sold in North America start with WAU.
Positions 4–8: Vehicle Descriptor Section (VDS)
These five characters describe the specific model and its features. Position 4 tells you the model line (for example, A4, A6, Q5, or TT). Position 5 indicates the body style and engine type. Positions 6–8 cover safety equipment, transmission type, and other mechanical details.
This section is where the VIN becomes harder to read without an Audi-specific decoder, because the codes vary by model year and market. For instance, a Q5 built in 2015 will have different codes in positions 4–8 than a Q5 built in 2020. If you need to know exactly what your car's codes mean, contact an Audi dealer with your VIN, or use the VIN lookup tool on the Audi website.
Position 9: Check Digit
Position 9 is a single digit (0–9) that acts as a security check. It is calculated using a mathematical formula applied to all the other positions in the VIN. If someone has altered the VIN, the check digit will not match the formula, and the VIN will fail validation.
You can verify your VIN's check digit yourself using an online VIN validator, or you can ask a dealer to confirm it. If the check digit does not match, do not buy the vehicle—it may have been in a major accident, rebuilt from salvage, or stolen and re-titled.
Position 10: Model Year
Position 10 is a letter that represents the model year. The code uses letters A through Y (skipping I and O to avoid confusion with numbers). The sequence repeats every 30 years. From 2010 to 2024, the codes are:
| Letter | Year | Letter | Year |
|---|---|---|---|
| A | 2010 | M | 2021 |
| B | 2011 | N | 2022 |
| C | 2012 | P | 2023 |
| D | 2013 | R | 2024 |
| E | 2014 | S | 2025 |
| F | 2015 | T | 2026 |
| G | 2016 | V | 2027 |
| H | 2017 | W | 2028 |
| J | 2018 | X | 2029 |
| K | 2019 | Y | 2030 |
| L | 2020 |
This is the easiest part of the VIN to read. If you see a letter that does not appear in the table above, the VIN may be incorrect or the vehicle may be older than 2010 (in which case you would use a different decoding method).
Positions 11–17: Vehicle Identifier Section (VIS)
The final seven characters are unique to your specific car. Position 11 identifies the assembly plant where the vehicle was built (Audi has factories in Germany, Hungary, Belgium, and other locations). Positions 12–14 typically indicate transmission type and other production details. Positions 15–17 are the serial number, which is never repeated on any other Audi.
These last seven digits are what make your VIN truly unique. Two Audis can have identical codes in positions 1–10, but positions 11–17 will always be different. This is why the serial number is useful for tracking recalls, service history, and ownership records.
How to use your Audi VIN for recalls and service
Once you understand your VIN, you can use it to check for open recalls on the National Highway Traffic Safety Administration (NHTSA) website at safercar.gov. Enter your VIN, and the site will show you any recalls issued for your specific model year and build configuration.
You can also use your VIN when scheduling service at an Audi dealer. The dealer can pull up your vehicle's complete service history, warranty information, and any technical service bulletins (TSBs) that explore to your car. If you are buying a used Audi, ask the seller or dealer for the VIN before you visit, so you can run a recall check and research the vehicle's history independently.
Frequently Asked Questions
Can I tell if an Audi is a salvage or rebuilt title just from the VIN?
No, the VIN itself does not indicate salvage or rebuilt status. However, if the check digit (position 9) does not validate, it is a red flag. To learn about a car has a salvage title, you need to run a vehicle history report through Carfax or AutoCheck, or contact your state's Department of Motor Vehicles with the VIN and title number.
What does the assembly plant code in position 11 tell me?
Position 11 shows which Audi factory built your car. Audi operates plants in Ingolstadt and Neckarsulm, Germany; Győr, Hungary; Brussels, Belgium; and other locations. Some buyers prefer vehicles from certain plants based on reputation, though all Audi factories maintain the same quality standards. Your dealer can tell you which plant code corresponds to which location.
If I change my VIN, will it affect my insurance or registration?
Altering a VIN is illegal in all 50 states and is a federal crime. It voids your insurance, invalidates your registration, and can result in criminal charges. If you suspect a VIN has been altered, report it to your state's DMV and local law enforcement when ready.
Can I decode my Audi VIN without going to a dealer?
Yes. Online VIN decoders specific to Audi can tell you the model, year, engine type, and assembly plant. However, some details—particularly the exact trim level and optional equipment—may require a dealer to confirm. Audi's official website also has a VIN lookup tool for owners.
