How this VIN pattern is read
A 17-character VIN carries two kinds of information: what was built, and which one it is. This page is the first kind — the nine highlighted positions.
| Positions | Characters | What they encode |
|---|---|---|
| 1–3 | WAU | AUDI AG · World manufacturer identifier |
| 4–8 | BC48H | Model, body style, engine and restraint system |
| 9 | × | Check digit — computed per vehicle, not part of the build |
| 10 | 5 | Model year — 2005 |
| 11 | × | Assembly plant |
| 12–17 | ×××××× | Production sequence number, unique to each vehicle |
NHTSA safety ratings
Crash-test results are published per model year and body style, so they cover the 2005 Audi A4 as a whole rather than this build alone.
Rollover

Where this data comes from
Specification fields are decoded from the manufacturer's filings in the NHTSA vPIC database, keyed on VIN positions 1–8 and 10. We publish the filed values as they stand and leave out anything the filing does not record.
Vehicle counts come from the 30 VINs of this build we have seen in dealer inventory. They are a sample of the road population, not a production figure.
