Would you mind sharing which piece of trim you needed to remove to check, and how difficult it was? We've had our SR+ for 3 weeks and my wife would kill me if I broke something.
The trim piece below the rear vents touching the carpet floor. I yanked on the bottom of it to remove.
I’d honestly be surprised this is the way to check if you have 2.5 or 3. It’s just what the guy earlier said so I was curious and checked what I had. I know the computer is on the firewall on the passenger side but haven’t ripped stuff apart to check.

Really? I've checked two of my friends cars, and the API returned APH3 (2.5) for both of them.
Yup... they’re returning the same option codes for all Model 3s... it’s bogus data.
Decoding Model 3 Option Codes
Minimal research here...so sometime in March Tesla decided to change the harness connector at this location to a different connector. It’s actually a connector you can use for diagnostics/can bus. The pin layout also changed from previous Model 3s. Does it mean HW3....I have no idea.
No to which part, Gigagrunt? There are like 3 contradictory statements in there. Appreciate your perspective!

Part catalog just has that listed as the main model 3 computer. As with HW3 on the Model X, it seems like the middle two digits don't always match. No mention of a REV02, however. Anyone taken apart a 2018 Model 3 to compare?

Blurry photo here Behold HW3 ( First pics ) !!!! But if you zoom in you can clearly see REV01. Still no 100% verification of HW3, but it definitely seems to be leaning that way.
Then again, just saw the screenshots here Tracking Autopilot HW3 Factory Installs & Upgrades - Does Your Car Have It?. REV03 seen back in the beginning of March, with a user claiming it was produced January 2018....

The model s/x mcu have a completely different design so you can't really compare to the 3. Here's a pic of mine and the console harness.

Thanks for the pictures. The first couple of digits of the serial number are supposed to tell you when the part was manufactured, so at the very least we know yours is 2019.
That "First pics" thread is a bit difficult to follow (since it starts out as an April Fools joke), but the pictures I linked are of a Model 3 MCU. And the Tesla Owners Online thread, that's also about Model 3.
I don’t know 100%. However, I have yet to see the firmware show up in VIN’s that I have interfaced with recently.
