A Audi 80 VIN is 17 characters. Positions 1–3 say who built it and where, 4–8 describe the body and engine, 9 is a check digit, 10 is the model year, 11 is the plant, and 12–17 are the serial number.

How to read a Audi 80 VIN
Every Audi 80 VIN follows the same 17-character layout:
| Position | Section | What it tells you |
|---|---|---|
| 1–3 | WMI | World Manufacturer Identifier — country, manufacturer and vehicle type. |
| 4–8 | VDS | Vehicle Descriptor Section — body style, engine, restraint system, series. |
| 9 | Check digit | A calculated digit that validates the whole VIN. Wrong digit = wrong VIN. |
| 10 | Model year | One character for the model year. Letters skip I, O, Q, U and Z. |
| 11 | Plant | The assembly plant that built the car. |
| 12–17 | Serial | Sequential production number of this exact vehicle. |
Audi 80 VIN prefixes, and when each one was used
Characters 1–3 are the World Manufacturer Identifier. Every Audi 80 we have on record, from 1988 to 1991, carries the same one — WAU, which makes it a quick way to confirm you are looking at a real 80:
| VIN starts with | Years seen | Built in | Vehicle type | VINs on record |
|---|---|---|---|---|
| WAU | 1988–1991 | Germany | Passenger Car |
Position 11 names the plant. On the Audi 80 it is not one number either — assembly moved between 2 of them over the years:
| Plant code | Years active | VINs on record | Share |
|---|---|---|---|
| A | 1988–1991 | 16 | |
| 1 | 1989–1989 | 1 |
Counted from the 15 dated Audi 80 VINs attached to NHTSA complaints — the largest such set for this model — with every code checked against the NHTSA manufacturer registry, so mistyped entries are dropped; the figures say how many records carry each code, not how many 80s left the line.
Model-year codes for the Audi 80
Position 10 carries the model year, skipping I, O, Q, U and Z. The alphabet comes round every 30 years, which the Audi 80 has not yet outlived — its 4 years still map one-to-one. All 4 model years of the Audi 80, 1988 to 1991, with the character each one carries:
| Model year | VIN character (position 10) | Same character as |
|---|---|---|
| 1991 | M | — |
| 1990 | L | — |
| 1989 | K | — |
| 1988 | J | — |
When two years share a character, the check digit and serial range tell them apart — that is what the decoder does automatically.
What a decoded Audi 80 VIN gets you
Reading the characters is the easy part — the reason to decode a VIN is what sits behind it. For the Audi 80 that is 17 owner complaints and every recall campaign NHTSA has on record, keyed to the same VIN you just read:
| Data | For this model | Source |
|---|---|---|
| Recall campaigns | 8 campaigns | NHTSA |
| Owner complaints | 17 filed | NHTSA |
| Fuel economy | 21 mpg combined (avg) | EPA |
| Model years covered | 4 years | ForCar catalog |
Where to find the VIN on a Audi 80
Four places on a Audi 80 carry it, and all four must read the same — a mismatch is where fraud shows itself first.
| Where | How to see it | Why it matters |
|---|---|---|
| Dashboard, driver side | Through the windshield, bottom corner | Easiest to check before you touch anything |
| Driver door jamb | Open the door, sticker on the pillar | Also lists tyre pressures and build date |
| Under the hood | Firewall or strut tower plate | Survives a windshield replacement |
| Title and insurance | Paper documents | Must match the car — a mismatch means fraud or a swapped panel |

Frequently asked questions
Is this Audi 80 VIN decoder free?
Yes — decoding a Audi 80 VIN costs nothing and needs no account. Beyond the year, plant and build characters you also get what NHTSA holds on the Audi 80 — 8 recall campaigns and 17 owner complaints — at no charge.
How many characters is a Audi 80 VIN?
Seventeen, on every Audi 80 built from 1981 onwards, when the 17-character format became mandatory in the US.
Why do two Audi 80 model years share the same VIN character?
Position 10 cycles through the alphabet every 30 years, skipping I, O, Q, U and Z. A 1995 and a 2025 car can carry the same letter. The check digit and serial range separate them.
Can a Audi 80 VIN tell me if the car was in an accident?
Not from the characters themselves — they describe how the Audi 80 left the factory, not what happened to it afterwards. Crash and title records sit in separate databases keyed to the same number. What is public are the 17 complaints Audi 80 owners filed with NHTSA, and those we do show. Run the number through our VIN check to see what is on the record for it.
Do the body and engine characters mean the same thing on every Audi?
No, and that is the usual mistake — positions 4–8 are assigned per model, not per brand. A letter that means one body on the Audi 80 can mean a different one on another Audi, and something else again on another marque.
What if the VIN on the dashboard doesn't match the door jamb?
Treat it as a red flag on any car, and on a Audi 80 check the prefix first: for the model year in question it should open with WAU, depending on when the car was built — anything outside that set did not come off a Audi 80. Beyond that, mismatched plates mean either a replaced panel or a tampered identity — ask for documents and verify before any money changes hands.
