SUL

The first three characters of every VIN are the World Manufacturer Identifier (WMI). The code SUL is assigned to FSC (Poland), with the country of manufacture Poland.

So any 17-character VIN that begins with SUL was produced by FSC (Poland):

SULZZZ0000000000000

The WMI only identifies the maker. To read the year, engine, plant and serial number, decode the complete 17-digit VIN with our free tool — then check which ECU it uses and what tuning services (DPF, EGR, AdBlue, DTC off, Stage) are available.
