Audi VIN Decoder & Check
Decode any Audi VIN free, then read the full vehicle history before you buy.
Buying a used Audi?
Audi is Volkswagen Group's luxury arm, based in Ingolstadt, Germany, and it built its modern reputation on quattro all-wheel drive, which it has offered since 1980. The US lineup runs from the A3 sedan through the Q7 and Q8 SUVs, plus the e-tron electric range.
Almost every used Audi in America started as a lease. They come off lease in waves, three years old with 30,000-some miles, and depreciation is steep enough that a five-year-old A6 can cost less than a new Jetta. Cheap German luxury is tempting. It is also exactly where repair bills and hidden accident history do the most financial damage, which is why an Audi VIN check pays for itself faster than most.
Audi history: what to verify before you buy
Every brand has its own used-market patterns. These are the ones worth checking on an Audi, and where the report answers each one.
Oil consumption on early 2.0T engines
The 2.0-liter turbo in many 2009 to 2012 models burned oil badly enough to trigger a class-action settlement and extended coverage. On cars from those years, service records matter, and the report's maintenance schedule shows what the factory expected at each interval.
Flood cars dressed as bargains
Luxury sedans with water damage get bought cheap at salvage auctions, dried out, and resold in states with looser title rules. The report follows the title across state lines, so a flood brand issued in one state still shows even after the car moves twice.
Structural repairs under new paint
Aluminum and mixed-material construction makes crash repair on an Audi expensive and easy to do badly. Reported accidents in the report include impact areas and damage severity where recorded, which tells you which panels deserve a closer look in person.
Transmission service gaps
The S tronic dual-clutch and older multitronic gearboxes need fluid services that lease drivers routinely skipped. The odometer history plus the factory maintenance schedule in the report lets you line up the miles against what should have been done by now.
How to decode an Audi VIN
Every Audi built since 1981 carries a 17-character VIN, and each position means something specific. Here is how to read one yourself, or paste it above and let the decoder do it in seconds.
Example VIN for illustration. Positions 1 to 3 identify the manufacturer, 4-8 describe the vehicle, 9 is the check digit, 10 is the model year, 11 is the assembly plant, and 12-17 are the serial number.
Positions 1-3: where your Audi was built
The first three characters are the World Manufacturer Identifier, assigned to a specific company, country, and vehicle type. This is the fastest answer to the question of which factory built the car.
| WMI code | Built in | Typically used on |
|---|---|---|
| WAU | Germany | Sedans and wagons such as the A4, A6, and S models |
| WA1 | Germany and Slovakia | Q-line SUVs such as the Q5, Q7, and Q8 |
| TRU | Győr, Hungary | Hungarian-built models such as the TT |
| WUA | Germany (Audi Sport) | High-performance R and RS models |
Common Audi manufacturer codes. Codes vary by model, plant, and era, so a code outside this table is not by itself a red flag. The free decoder above resolves any Audi VIN to its exact factory record.
Positions 4-8: what the vehicle is
Audi uses positions 4 through 8 to encode the platform, engine, restraint system, and model series. This is how the report distinguishes a front-drive A4 from a quattro car with the same paint and trim.
Position 9: the check digit
A number computed from all the other characters using a federal formula. If someone alters a VIN by hand, the math stops working. It is the first thing our decoder verifies, and a failed check digit on a listing is a walk-away signal.
Position 10: the model year
One character encodes the model year. Letters and digits alternate in a 30-year cycle, so the same code serves two eras:
Year codes repeat every 30 years. Position 7 settles the cycle: on 17-character VINs, a letter there means the vehicle is from 2010 or later, a digit means 1981-2009.
Positions 11-17: plant and serial number
Position 11 names the assembly plant within the factory network, and the final six characters are the serial number, unique to this one Audi. Together with the rest of the VIN, they make the identity impossible to share honestly, which is exactly why cloned VINs are worth checking for.
