After the W1K WMI, positions 4–8 describe the model, body and engine; position 9 is the mod-11 check digit; position 10 is the model year; position 11 is the assembly plant; and positions 12–17 are the serial number. See the full 17-digit VIN format.
W1K is a Mercedes-Benz WMI. Every VIN beginning with W1K was built by Mercedes-Benz and decodes to that make.
The first character W places the manufacturer in Germany (Europe region) under the VIN standard.
No. They are synthetically generated but checksum-valid and use the real W1K WMI, so a decoder returns Mercedes-Benz. No real vehicle's VIN is used.
