Audi VIN Check
Audi's quattro all-wheel-drive system revolutionized rally racing in the 1980s. The brand sits in the Volkswagen Group premium tier alongside Porsche and competes with BMW and Mercedes-Benz.
Today every Audi built for regulated markets carries a 17-character VIN. Positions 1–3 (WAU, WA1, TRU and related codes) identify the maker; positions 4–8 describe the vehicle; positions 9–17 cover validation, year, plant, and serial. WAU and WA1 are the primary Audi WMIs; TRU indicates the Győr, Hungary engine and assembly plant.
On this page you can paste any Audi VIN into the decoder above. We check format (no I, O, or Q), verify the ISO 3779 check digit, resolve the WMI against our registry, and apply Audi-specific rules researched from NHTSA vPIC, ISO standards, and manufacturer documentation.
Audi WMI prefixes we decode
| WMI | Country | Notes |
|---|---|---|
WAU | Germany | Audi cars |
WA1 | Germany | Q-series SUVs |
TRU | Hungary | Győr plant |
Remember: a VIN decode shows how the vehicle left the factory. It does not show accidents, title brands, odometer history, or prior owners.
How to Read a Audi VIN
Here is how DecodeAnyVin interprets a Audi VIN, and how you can read the same characters manually.
Reading a Audi VIN by hand
Positions 1–3 (WMI). Expected prefixes include WAU (Germany), WA1 (Germany), TRU (Hungary). WAU and WA1 are the primary Audi WMIs; TRU indicates the Győr, Hungary engine and assembly plant.
Position 4 (Vehicle Line). Common mappings in our decoder: brand-specific line codes.
Position 5. Usually series, trim, or drivetrain detail for Audi.
Position 8 (engine / related). Examples: engine / market codes that vary by year.
Position 9. ISO 3779 check digit — DecodeAnyVin validates this automatically.
Position 10. Model year on the standard 30-year letter/digit cycle.
Position 11. Assembly plant. Examples: A = Ingolstadt, Germany, B = Brussels, Belgium, D = Bratislava, Slovakia, E = Emden, Germany, G = Graz, Austria, K = Rheine, Germany.
Positions 12–17. Production serial unique to that plant line.
Audi-specific quirks to watch
- VDS codes (4–8) can change when Audi launches a new platform — charts from a different decade may mislead.
- North American market VINs follow FMVSS 565; vehicles imported privately may still use the same WMI system but different catalog data.
- Always cross-check the decoded plant and engine against the door-jamb sticker before ordering expensive parts.
Decoded attributes are informational. Confirm engine, trim, and drivetrain against the window sticker, build sheet, or a dealer before purchase, insurance, or registration decisions.

Frequently Asked Questions — Audi VIN
Where do I find the VIN on a Audi?
Driver's side dashboard, door jamb, and Audi service portal.
What does the WMI WAU mean on a Audi?
WAU is a World Manufacturer Identifier used on Audi vehicles. WAU and WA1 are the primary Audi WMIs; TRU indicates the Győr, Hungary engine and assembly plant.
Has Audi VIN encoding changed over time?
Yes. Like most makers, Audi revises Vehicle Descriptor Section codes when platforms change. Treat older charts carefully and confirm critical attributes against the window sticker or build sheet.
Can I decode a Audi VIN for free on DecodeAnyVin?
Yes. Paste your 17-character Audi VIN into the form on this page. We validate the ISO 3779 check digit, resolve the WMI, read the model year and plant, and apply Audi-specific rules for positions 4–8 where available — no signup required.
Does a Audi VIN show the engine?
Often yes. On many Audi lines, position 8 (sometimes nearby VDS positions) encodes engine family. Coverage is strongest for high-volume models such as A4 and A6; exotic or late-cycle codes may need dealer confirmation.
How do I know a Audi VIN was not altered?
Run the check digit (position 9). Example structure: WAUZZZ8V19A123456. Also match the windshield VIN to the door-jamb label and reject plates that look restamped or glued. A decode cannot prove title status — only factory identity.
Is the model year on a Audi VIN always the calendar year?
No. Position 10 is the manufacturer's model year on the ISO 30-year cycle. A vehicle built in autumn may already carry next year's code. Use it as the factory model year, not the build calendar date.
Which Audi models does DecodeAnyVin support?
Any Audi with a standard 17-character VIN (typically 1981+), including A4, A6, Q5, Q7, Q8, e-tron, RS models. WMI and year/plant decode work broadly; detailed trim/engine depth depends on documented VDS rules for that platform.
