SU9

The first three characters of every VIN are the World Manufacturer Identifier (WMI). The code SU9 is assigned to Solaris, with the country of manufacture Poland.

So any 17-character VIN that begins with SU9 was produced by Solaris:

SU9ZZZ0000000000000

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.
