If you use a 3rd party inventory site, like tesla-info or tesla hunt but I imagine others too, they give you the option to look at/search on the build codes. These breakdown all the main components and cover everything from the actual battery, motor versions, autopilot hardware, charge port hardware etc. We can see when the Low voltage battery changed and 5ge Ryzen processor MCU arrived.
They think the “no USS” build code has been identified, but after that it appears there’s only one codes that is yet to be decoded, TY0C, and I think that’s likely to be tyres. AP HW2, HW2.5 etc all had their own codes, and no radar also had a code. It doesn’t look promising that any of the cars have a materially different camera, that’s not to say it doesn’t. Here’s an example for a new inventory MY.
