New new refreshed Model S (delivered in late June) with VIN 145xxx almost always has a buzzing noise, heard loudest near the driver's side front wheel. This is heard after the car is parked, and off/locked for a while. It's NOT the AC and it's not the car waking up when it detects the keyfob (the keyfob is well away from the car).
I realize this is probably the thermal battery management coolant pump but it seems to be running all the time, and even when it's not very hot or cold outside: I've heard it in a parking garage, after a cool summer evening rain with external temps of 16C (60F) in the shade (as in this video). The guys installing my paint protection film in a cool, shaded, airconditioned installation shop commented on it as well.
This noise is definitely more noticeable and more frequent than my original S (VIN 16000's). Thus, I'm no stranger to Teslas, and this is definitely different. I've sent the video to my local SC and they are looking into it, but I thought I'd ask others if their refreshed S's are doing the same thing.
Here's a video. Again, the AC is NOT on and the car is parked, keyfob inside the house and far from the car, 16C outside after a cool rain in the shade:
While I don't really get bothered by the noise, I wonder if it's adding to vampire drain, excess load on the coolant system, or some other issue. It certainly flies in the face of the concept that Teslas are silent cars, and ironic that a Tesla that is off is noisier than an ICE car!
On a related but definitely separate note, I think the AC in this model is also louder than my prior S. The older VIN 16000 S had the AC blanket fix to muffle it, which made a difference, but the newer VIN145xxx refreshed S's AC is quite loud when running.
