Can people with a M3 please do a test for me

[Tigermad]

Can people with a Tesla 3 please do this test for me. Get in your car, turn off the climate and sit there. Is there any sound coming from the vents or the front of the car?

If you hear a sound can you please post which version you have. Thanks

No sound from 2020 SR+ without heat pump

Funnily enough just this afternoon i took my daughter to the doctors and waited in the car for her - turned off climate because the air con was a little too cool and sat there with the window open enjoying the sun - not a peep out of the car for 20 minutes. 2020 M3P

Thanks. I think you need to have left it for a few hours and try it as soon as you get back in. First thing in the morning for example

No any sound. LR March 2020

In this weather I turn off the HVAC and it doesn't make any noise when I get into the car in the morning.
I also leave the windows down and the drivers door not fully closed when the car is on the drive and there is no noise from the HVAC system.

It all depends... After supercharging, for example, there is still external fan noise even with climate control off for sometime after.

The car likes to make noises whenever it feels like it, sometimes regardless of driver.

The AC fans often run unprompted, particularly after having been on for a while and then switched off. I was under the impression it ran as fan-only to dry out the air ducts to prevent condensation and associated funky smells. This is a great idea - something my Lexus CT could really do with.

Mine often sits plugged in and from time to time I have heard some whirring going on. I don't have cabin overheat on and all systems would be expected to be dormant. I would be happy to think it was doing something sensible such as you describe!

2021 LR model 3 with heat pump. There is a slight hum from the dash without the fans. Kind of reminds me of a cpu fan or power supply fan on PC. You’d have to listen for it but I thought it would be related to cooling the FSD and MCU2 computers. It’s quiet enough that it’s never bothered me. I did have the heat pump thud/rumbling issue when the A/C was cooling the cabin and car stationary. That was annoying but eventually went away with a software update some months ago. Someone mentioned that was an issue with compressor ramping up too quickly

Does it sound like this?

I posted in another thread that my MIC 2021 SR+ like to make this noise randomly after short drives (other times its completely silent)

I'm driving a 2021 M3 and when I turn off the AC, only silence.

May 2021 M3 LR AWS.
Exactly as JS77 and Tigermad have posted.
It seems to have a mind of its own, I suspect it is to do with the HAV systems for the battery and the cabin.

When you park after driving, I think the cooling system still runs for a while to remove any potential hot spots in the battery pack. The fan in the frunk seems to run for half an hour or so on my 2020 SR+

My 2021 MIC SR+ seems to run like a helicopter about to take off when the temperature is what it’s been in UK for the last few days (and the plastic seats still take the skin off my legs if I’m wearing shorts)… please don’t ask me to not wear shorts, it’s not a pretty sight ( or one to be proud of)

It’s not after driving on mine. It’s there every single time I get in the car

Do you have the heat pump version?

 

[Tigermad]

@Billbrown1982 does your car do this please?

Sounds like the external noise speaker to warn pedestrians
