Common Warnings in an Audi VIN Decoder
If the Audi VIN decoder shows a warning, here is what it means and what to do.
Outstanding Finance on an Audi
This means money is still owed on the car. If you buy an Audi with unpaid finance, the lender could take it back. Get a full history report to confirm the finance status.
Audi Marked as Stolen
This means the car is listed as missing or stolen. Do not buy it. Check a full report to confirm the stolen status before you go any further.
Mileage Problems on an Audi
Sometimes mileage is rolled back to look lower. This can hide heavy use. A full history check compares past readings to spot mileage issues.
Why Decode an Audi VIN Before You Buy?
An Audi VIN check helps you make sure the car matches its papers. It can find problems early and save you money when buying a used Audi like the A1, A3, A4, A6, Q3, Q5, Q7, TT and more.

How an Audi VIN Is Structured
Every 17-character Audi VIN has three parts that tell you where the car was built, what it is, and its unique serial number:
WMI (World Manufacturer Identifier)
Shows country and maker. Common Audi WMIs include WAU (Audi passenger), WA1 (Audi SUV), TRU (Audi TT, Hungary) and WUA (Audi Sport).
VDS (Vehicle Descriptor Section)
Characters 4–9 describe model/body/engine and safety systems. The 9th is the check digit.
VIS (Vehicle Identifier Section)
Characters 10–17 include model year, plant code and the serial number.
Check Digit (9th)
Checks that the VIN is valid. If it fails, the VIN may be typed wrong.
Where to Find the Audi VIN
Audi puts the VIN in several safe places. Check these common spots:
Dashboard / Windscreen
Look through the windscreen at the driver’s side lower dashboard for the VIN plate.
Driver’s Door Pillar
Open the driver’s door and check the inner B-pillar sticker.
Under the Bonnet
You may see the VIN stamped on the firewall or slam panel. It’s also on the V5C/logbook and insurance papers.

Audi VIN Questions & Answers
Popular Audi VIN and chassis number questions, answered:
Do Audis always use 17-character VINs?

Which VIN prefixes are common on Audis?
You’ll often see WAU/WA1 (Germany), TRU (Hungary) and WUA (Audi Sport). The rest of the VIN shows model year, plant and serial.
Can you decode Audi option codes?
Audi option codes (PR codes) list factory options like seats or brakes. They’re separate from the VIN; your full report may include decoded options where available.
Frequently Asked Questions about Audi VINs
Where can I find the Audi VIN?
Common VIN spots include: driver’s side dashboard (seen through the windscreen), the driver’s door pillar/B-pillar sticker, under the bonnet on the slam panel or firewall, and papers like the V5C/logbook and insurance.
What do common Audi VIN prefixes mean (WMI)?
Audi WMIs often include WAU (passenger cars), WA1 (SUVs), TRU (TT, Hungary) and WUA (Audi Sport). These three characters show the maker and country.
Which character shows the model year on an Audi VIN?
The 10th character shows the model year. Letters/numbers are used; I, O and Q are skipped to avoid confusion.
Can an Audi VIN tell me the engine and trim?
The VIN shows the line, body and engine family in the VDS. Exact trim/options are best confirmed via Audi PR option codes and a detailed report.
Are Audi option codes part of the VIN?
No. Audi PR codes list factory-fitted options. They are separate from the VIN and appear on data stickers or service records.
Is the chassis number the same as the VIN on an Audi?
For modern Audis, the 17-character VIN serves as the chassis number. Older/imported vehicles may differ, but we’ll decode whatever you enter.
Can I decode a pre-1981 or imported Audi VIN?
Yes. We try to parse legacy/import formats, though detail can vary. For full checks, run a complete Audi history report.
Will the Audi VIN decoder show theft, finance and write-off status?
The free decoder gives identity and build info. Upgrade for stolen checks, outstanding finance, write-off status (Cat S/N), mileage issues and more.
Does an Audi VIN include the plant code?
Yes. The VIS (characters 10–17) includes model year, assembly plant code and the unique serial.
Why does my Audi VIN come up as invalid?
Make sure it’s exactly 17 characters with no I, O or Q. Errors in the 9th character (check digit) can also flag invalid. If it keeps failing, send us a photo of the VIN plate/sticker.
