How to read a Audi S4 VIN — every digit explained
Every Audi S4 carries a unique 17-character VIN stamped at the factory. Each position is a code — together they spell out where, when and how your car was built. Here's exactly what every digit means.
- WMI (1–3) — country & manufacturer. Tells you it's a Audi and the country it was built in (real Audi codes below).
- VDS (4–8) — model, body style, engine, trim & restraints. The 8th digit is the engine code.
- Check digit (9) — a math check that proves the VIN is genuine.
- Model year (10) — the year it was built (e.g. R = 2024, S = 2025).
- Plant (11) — which factory assembled this S4.
- Serial (12–17) — the unique sequential production number.
- GermanyWA1 · WAU · WU1 · WUA
- HungaryTRU
Digits 4–17 — the engine code (8th), model-year letter (10th) and plant — follow the universal SAE standard, identical on every car. For the full year-code table (2001–2026), country codes and where the VIN is stamped on your S4, see the complete guide to reading a VIN.

A Audi S4 tends to depreciate faster than average. A typical example keeps roughly 37% of its value after five years — losing about 63% to depreciation. Fuel, maintenance and insurance add to the total cost to own.
| Age | Value retained | Est. resale value | Lost to depreciation |
|---|---|---|---|
| Year 1 | 75% | $22,500 | −$7,500 |
| Year 2 | 63% | $18,900 | −$11,100 |
| Year 3 | 53% | $15,900 | −$14,100 |
| Year 4 | 44% | $13,200 | −$16,800 |
| Year 5 | 37% | $11,100 | −$18,900 |
What goes into the five-year cost to own:
- Depreciation — the biggest cost: this S4 loses about 63% of its value over five years. See the full depreciation curve by age.
- Fuel — ≈ $16,000 over five years at roughly 15,000 miles a year.
- Maintenance & repairs — routine service, tires and wear items as the S4 ages.
- Insurance — varies by driver, state and trim; get a quote for your exact figure.
Resale & depreciation are ForCar estimates from typical segment value-retention curves — not a live market quote. Fuel from EPA fueleconomy.gov at ~15k mi/yr.
How much is a Audi S4 to insure?
A Audi S4 costs about $2,094 a year to insure for a typical driver on full coverage — roughly 46% above the average car. That's from its real HLDI insurance-loss index (146, where 100 = average car); your own rate moves with state, age, record and coverage.
Estimate = US-average premium × the S4's HLDI loss index. See Audi insurance cost by model, cost by state, or compare any car.
