21 model S heater noise

Anyone with this noise when heater is on? Noise stops as soon as climate control is turned off

Have the same thing. Just started to get a little quieter as I type, but it’s weird

Damn. MCU3 is fast.

I live in SoCal so we don't need heaters much over here, but for the sake of testing I put mine on "HI" and let it run for a while. It's quiet as a mouse outside the car, inside the blower fan is louder than anything else in the car by far.
For the record my car just took the .7 update.
Also, the (refresh) heater heats the interior better than my previous 2 Model S's that were a 2014 & 205.

I just started to notice this just recently, since last two weeks. I do have the latest software.

Sounds like a mechanical issue with the octovalve pump. I would raise a service issue for sure.

Reminds me of a fan with a noisy/loose bearing. Is the Octovalve such advanced alien technology that they no longer need something so crude as a fan? Elsewise, may need to upgrade that Sunon to a Noctua... [j/k]
