BMW 328d VIN prefixes, and when each one was used
Every BMW 328d we have on record, from 2014 to 2015, opens with the same three characters, WBA:
| VIN starts with | Years seen | Built in | Vehicle type | VINs on record |
|---|---|---|---|---|
| WBA | 2014–2015 | Germany | Passenger Car |
Position 11 names the plant. On the BMW 328d it is not one number either — assembly moved between 2 of them over the years:
| Plant code | Years active | VINs on record | Share |
|---|---|---|---|

Where to find the VIN on a BMW 328d
A BMW 328d VIN normally opens with WBA; 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 |
