Hi, I took delivery of my Model 3 (#4000-ish) last week and there are 2 things that really bother me about this car. One is the ridiculously loud blower fan, the other is I have an intermittent high pitch beeping, which sounds a lot like morse code, in the cabin. I can hear it driving at low speeds and of course when the car is sitting. I noticed that the sound can be affected by the LED headlamps. If I sit in the car, and switch the headlamps from AUTO to OFF, the beeping stops for a bit, and then will eventually go back into its 'morse code' like pattern. If I switch the lights from OFF to PARKING, the intermittent beeping turns into a constant beeeeeeeeeeeep, which sounds a lot like tinnitus or ringing in the ears. If I toggle between OFF and PARKING and OFF and PARKING, I can control the long beep. It sound a lot like a piezo buzzer. I'm guessing this has to do with the LED light drivers on the headlamps. If I switch the lights into AUTO, or ON, the beep is still there, but it is masked a bit by the LED cooling fans on the lights. Putting the lights in PARKING keeps those fans off so you can isolate the beep. I'm 33 years old, and have better than average hearing. My girlfriend can hear it, but my parents cannot. Does anyone else have this issue?
