Common Audi WMI prefixes (VIN positions 1–3)
| WMI prefix | What it identifies |
|---|---|
| WAU | Audi passenger car, built in Germany |
| WA1 | Audi SUV (Q5, Q7), built in Germany |
| WUA | Audi Sport (RS) model, built in Germany |
| TRU | Audi sports car, built in Hungary |
How an Audi VIN breaks down
Every Audi built since 1981 carries a 17-character VIN under the ISO 3779 standard. Positions 1–3 are the World Manufacturer Identifier — a German-built Audi car commonly opens WAU, a German-built SUV WA1, and an RS performance model WUA. Positions 4–8 encode the model line, body and engine; position 9 is the check digit; position 10 the model year; position 11 the plant; and 12–17 the sequential build number.
Because the engine and trim are described in positions 4–8, two same-year A4 or Q5 models can carry different descriptor characters depending on engine (40 TFSI vs 45 TFSI) and quattro drivetrain.
Decode vs. history: what the VIN can and can't tell you
Decoding an Audi VIN reveals the factory build — year, engine, plant and trim. It won't show what happened after the sale. For salvage, accident, flood and odometer brands, run the same VIN through a history report drawing on NMVTIS and state-DMV records.
