The same build, other model years

Audi used the VIN pattern WAU5ULFF for 3 model years. Nothing but the year changes between these pages, so the price gap between them is depreciation on an identical car.

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 5ULFF Model, body style, engine and restraint system
9 × Check digit — computed per vehicle, not part of the build
10 K Model year — 2019
11 × Assembly plant
12–17 ×××××× Production sequence number, unique to each vehicle

39 vehicles carry this build

Every VIN we have decoded to WAU5ULFF-K shares the specification above.

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 39 VINs of this build we have seen in dealer inventory. They are a sample of the road population, not a production figure.
