Recent heat pump failures - software issue?

Ok. It makes sense now. Even I don't own a heat pump equipped Tesla but my cars are getting old, so I want to trade in soon. In addition, it's boring to stay in California after a while, I want to visit Canada too, so that's why I am interested in the fix prior to my commitment to future heat pump equipped Tesla car purchases.
Critical Tesla heat pump fixes coming in 2021.44.30.6 software update [Update]
Tesla has started deploying their latest software update, 2021.44.30.6 to internal employee cars today. The first download was spotted by update tracker Teslascope on a Model S Plaid in Florida this morning. We noticed a […]

might as well do a "bug report" with the error on screen, although I'm pretty sure they'll be monitoring it closelyHey, I have just received the 30.6 update, and was extremely happy about it (didn't expect to get one so fast), but... It didn't help, all the symptoms are same
When you say "the symptoms are the same", what symptoms are you having?Hey, I have just received the 30.6 update, and was extremely happy about it (didn't expect to get one so fast), but... It didn't help, all the symptoms are same
Only cold air is blowing, error saying "Cabin climate control system requires service" and VCFRONT_a447 error in the alerts list. Also, when AC is trying to start, there's the sound exactly (the sound itself and the intervals) like in this video from another M3 owner: https://forum.teslaservice.kiev.ua/...6215.MOV.f292b594d35fda8cdd1bd996e2a4778f.MOV
Service technicians replied to me and have proactively ordered a new compressor and supermanifold though they weren't exactly sure it would solve the issue. The fact they ordered both has me thinking they've iterated on the design and a newer one is available. Otherwise what are the odds both parts would require replacement? Pure speculation though.
The update is being offered to me this evening. I haven't had any heat pump issues. The avg outside temp has been in the upper 20F - 40F, cabin temp set to 68F, seat heat set to medium, steering wheel heat on. The regen braking however is nearly absent on cold mornings, and is reduced throughout the day.
Some things can't just be a "software" issue, when it's happened to last year's models and this year's models that were just recently delivered (mine is barely 4 month old). I get how some people are so into "OMFG, my car just got better with a OTA update", but I'd rather that if it's a hardware issue, they recognize that it's a hardware issue, recall it, and fix it, then say here's a OTA update to "fix"/ignore sensors until winter is over and you forget about it until next winter

I think it is both hardware and software. They interated on the hardware and so those that don’t have the latest are subject to both possible hardware and software issues. According to what the techs told me my April 2021 MYLR build has the latest hardware so they think the issue I experienced was the “software” only issue.
I think it was sometiMe around when my build came out when the MY switched to the latest hardware but I’m just speculating.
Transport Canada looking into this now.

It received only 9 cases. That seems to be too few to be any statistically significant.
