Every Audi A4 (2017–2023) carries a 17-character VIN that begins with the WAU WMI. The A4 is a gas sedan; this page shows what each character of a Audi A4 VIN means and gives 4 checksum-valid sample VINs you can drop straight into test fixtures. Synthetic — not real: no scraping, no real-owner data. The generator below is pre-filtered to the A4.
Each sample below is built from the real WAU WMI and the A4's descriptor, so it decodes to a Audi A4 of the right model year:

Worked on the sample WAUENAF49HN573059 — a 2017 Audi A4:
| Position | Section | Value | What it tells you |
|---|---|---|---|
| 1–3 | WMI | WAU | Marks the VIN as Audi, built in Germany |
| 4–8 | VDS | ENAF4 | Descriptor for the A4 — sedan body, gas powertrain |
| 9 | Check digit | 9 | Mod-11 checksum over the other 16 characters |
| 10 | Model year | H | Code H = 2017 |
| 11 | Plant | N | Assembly-plant code |
| 12–17 | Serial | 573059 | Sequential production number |
Positions 1–3 of every Audi A4 VIN read WAU — the World Manufacturer Identifier that marks the vehicle as Audi, assembled in Germany (Europe). After the WMI, positions 4–8 (ENAF4 in our seed) describe the A4 itself; see the full 17-digit format.
Position 10 encodes the model year. For the A4, 2017 is code H and 2023 is code P. See the 2023 year code or the check-digit math.

A Audi A4 VIN is 17 characters starting with the WAU WMI, for example WAUENAF49HN573059. Positions 4–8 describe the A4, position 9 is the check digit, position 10 is the model year, and 12–17 are the serial number.
Read it left to right: WAU is the Audi WMI, positions 4–8 are the A4 descriptor, position 9 verifies the VIN via a mod-11 checksum, position 10 gives the year, position 11 the plant, and 12–17 the serial. Paste any VIN into the decoder to do it automatically.
The A4 in our seed uses the WAU WMI (Germany). Any VIN beginning with WAU decodes to Audi.
No. They are synthetically generated but checksum-valid, use the real Audi WAU WMI, and carry the A4's descriptor and a valid year code — so a decoder returns a Audi A4. No real vehicle's VIN is used.
