I think it's only the newer years that send the VIN? Can't say for sure. I've been told that the system is supposed to be made smarter so it knows how many monitors a certain car is supposed to have (to catch a "delete" tune), but the inspection system is so far behind I doubt they will. The state just wants the money (shops make almost nothing from doing them).I don't know if they do it over there, but over here they won just look at the readiness monitors, they need the ECM to supply the VIN to their computer, then it'll look at monitors. Almost failed once because it wouldn't connect.
They scan the bar code (registration or door jam) to check the VIN. In 08 they didn't do plug in OBD inspections on diesels in NY so I'm guessing that's where the info came from? It started around 2011 if I remember correctly?Had to look at one of my old inspection receipts from 2008.
My 03 Jetta did give it the Vin.
