I am trying to figure out where the this low frequency rumbling and noise is coming from in my 2021 Model 3. I get it every 40-60 seconds when I park (you do get it while driving as well but you don’t notice it as much).
In some posts I’ve read that this is normal in the 2021 models and that it is caused by the Heat pump. Other posts suggest that this happens on pre-model 2021 M3 as well when there is an imbalance in the condenser fan (?) and should be fixed.
So I thought I do a poll. If most 2021 M3 owners have this rumble and noise and hardly any pre-2021 owners then it is clear it is most likely the heat pump. If you get both 2021 and pre-2021 owners complaining (but in a smaller percentage then the ones that don’t have it) then it is clear there is something wrong and this is not normal.
