Where to find the VIN on a Audi 4000
A Audi 4000 VIN normally opens with WAU; the full number sits in four places, and all four must match.
| 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 tire 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 |

Where was my 4000 built?
Position 11 names the plant. Across 8 dated Audi 4000 VINs it reads A 100%.
What does position 4 mean on a Audi 4000 VIN?
It is part of the maker's own build code, so read it against this model, not a generic chart. On 2 Audi 4000 VINs here, Z is the most common character in position 4, on 50% of them.
What if the VIN on the dashboard doesn't match the door jamb?
On a Audi 4000 check the prefix first: most genuine ones open with WAU. A plate that starts with anything else, or disagrees with the other copies of the number, needs documents checked before any money changes hands.
