How to read a BMW M340i VIN
Here is a real 2026 BMW M340i VIN from our database, split into its parts:
VIN 3MW59FT06T8G27691 — decoded free on its own report page.
| Position | Section | What it tells you |
|---|---|---|

| 4–8 | VDS | Vehicle Descriptor Section — body style, engine, restraint system, series. |
| 9 | Check digit | A calculated digit that validates the whole VIN. Wrong digit = wrong VIN. |

BMW M340i VIN prefixes, and when each one was used
The BMW M340i VINs on record carry 2 different prefixes. The main one is WBA (Germany, 2020–2022), then 3MW (Germany, 2020–2022):
| VIN starts with | Years seen | Built in | Vehicle type | VINs on record |
|---|---|---|---|---|
| WBA | 2020–2022 | Germany | Passenger Car | |
| 3MW | 2020–2022 | Germany | Passenger Car |
Position 11 names the plant. On the BMW M340i it is not one number either — assembly moved between 3 of them over the years:
| Plant code | Years active | VINs on record | Share |
|---|---|---|---|
| F | 2020–2022 | 33 | |
| 8 | 2020–2022 | 21 | |

Where to find the VIN on a BMW M340i
A BMW M340i VIN normally opens with 3MW; the full number sits in four places, and all four must match.
| Where | How to see it | Why it matters |
|---|---|---|
| Dashboard, driver side | Through the windshield, bottom corner | Easiest to check before you touch anything |
| Driver door jamb | Open the door, sticker on the pillar | Also lists tire pressures and build date |
| Under the hood | Firewall or strut tower plate | Survives a windshield replacement |
| Title and insurance | Paper documents | Must match the car — a mismatch means fraud or a swapped panel |

Frequently asked questions
Is this BMW M340i VIN decoder free?
Yes, with no account. Besides the year, plant and build characters it shows 14 recall campaigns and 71 owner complaints NHTSA holds on the BMW M340i.
Why does my M340i VIN start differently from another M340i?
Because the BMW M340i was built under several maker codes, by plant and period. Across the BMW M340i VINs on record we see 2 of them: WBA (2020–2022), 3MW (2020–2022). Each is genuine for its years.
What year is my M340i by its VIN?
Read position 10: a 2026 M340i carries T, a 2025 M340i carries S, a 2024 M340i carries R.
Where was my M340i built?
Position 11 names the plant. Across 71 dated BMW M340i VINs it reads F 46%, 8 30%, A 24%.
What does position 4 mean on a BMW M340i VIN?
It is part of the maker's own build code, so read it against this model, not a generic chart. On 81 BMW M340i VINs here, 5 is the most common character in position 4, on 63% of them.
What if the VIN on the dashboard doesn't match the door jamb?
On a BMW M340i check the prefix first: most genuine ones open with WBA or 3MW. A plate that starts with anything else, or disagrees with the other copies of the number, needs documents checked before any money changes hands.
