Fremont has produced at least a handful of them with a heat pump.
Exclusive: Several Model 3 with Heat Pump & Octovalve Produced at Fremont Delivered to Tilburg
We need someone with a very recent build date to confirm if any of these updates have made it into production.
I'm getting my LRAWD this Sunday and it's a 800XXX vin. Wonder if that is recent enough. Is there a easier way to tell if the heatpump is installed or not without opening up the insides of the car?
