Recent heat pump failures - software issue?

[rypalmer]

I'm in Colorado with a July 2020 MYLR and the heat pump has always worked great. Yesterday got a VCFRONT_a531 error. The SC's estimate says they are going to replace both the compressor and super manifold. That seems intense. The heat is still working somewhat (I'm not sure exactly how 'bad' it is).

I got this error two days before my HVAC stopped working completely. I'd say let them... and avoid the very cold until they do.

I wonder what version this is talking about:

There is one car where 30.8 is currently installed. Maybe that?

I assumed the software fixed are for those heat pump that haven't fail yet.. otherwise, if your heat pump didn't get fix by the OTA , you have a hardware failure..

It’s maybe. If we think that only 4 days ago they acknowledged the issue and talked about a SW update. I mean, you need testing minimal QA before sending an OTA. It could be that it takes a bit more, and all the other fixes where just V11 bugs

In case you guys didn’t see the latest from elon

In BC interior during -35C, the resistance heating looking pretty good at the moment....

Value of used non-heat pump equipped Model 3s just went up a little bit

I’m sure 486 processors were coveted for a short time during the pentium FPU bug too

I had to work on finding media about the Model Y shutters and finally landed on Munroe

Of course everything is best that any other. Also removed one bolt.

Any developments so far? Did any of the failed ones came back?

2021.44.30.10 is out there already

My car still has the error. Software 2021.44.30.7. Going into the SC on Friday for new compressor and super manifold.

Here's hoping the process is smooth and you never have any HVAC issues again

Update on my end.. Tesla is going to haul my car to be serviced, and provide a rental car in the mean time. Really happy they've been able to do a little better than a no-heat drive to Halifax weeks away.

Glad to hear you've got some progress planned. Hopefully, they'll get it sorted quickly and satisfactorily. Let us know how it goes.

They've rescheduled my appointment from tomorrow to the 28th because of missing parts...
Edit: I asked them what parts they where going to change via the chat...

In my case it feels kind of odd because I never had heat pump problems before (including -12 C w/ snow) until this error (which arrived before the problems). It's almost like an attempt to fix someone else's problems via software bricked my heat pump that was previously OK

@rypalmer is that your experience as well? (no problems until the 2 days after error)

Well, they did answer me that they are cancelling the appointment because I don't have the .7 SW and asking me to test if it's solved with the upgrade. Somehow disappointed.
