How to read a BMW 840i VIN — every digit explained
Every BMW 840i 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 BMW and the country it was built in (real BMW 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 840i.
- Serial (12–17) — the unique sequential production number.
- Germany3MF · 3MW · 5UM · WAP · WB1 · WB3
- USA4US · 5UX · 5YM
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 840i, see the complete guide to reading a VIN.
