Odd buzzing sound coming from the dash

I hear this too, but not to the extent that you do. I hear it every now and then. Looking forward to what others have to say.

 

My 3 year old Tesla started doing this about a year ago. It comes from the left drivers vent and seems like it might be a harmonic vibration.

 

Probably unrelated, but there is a cooling fan behind the instrument display. On my 2013 S85, it started intermittently buzzing and was failing. Replaced and all good now.

 

I recall a post where there was a paper label in the duct that comes unglued and then the fan strikes it.

 

I have a 2016 S90D and I am getting a similar sound from the left from driver's area only when I'm traveling at highway speeds and on parts of the road with not so smooth asphalt which causes more vibrations in the car.

 

12/2015 85D here.

I heard a similar noise in mine yesterday by not quite as loud. Mine is a low level whirring noise which also goes away when the AC is off. The service center guy took a listen and said its normal. Apparently a recent firmware update increased the power from the AC (due to complaints it wasn't cold enough) which can explain the noise.

Additionally it's now hotter outside. They said the AC is also responsible for cooling the battery, so if it is hotter outside it will be louder? Who knows... would like to hear what they have to say about yours.

 

Have the same thing. Definitely not normal. Wrote about it in separate post: First bad day in the X

Couldn't post the sound file. But have exactly that. Happens more/gets louder when I'm stopped. Have an appt for Tuesday and will get it checked among a couple other minor things. Will let you know. But if I had to bet, id go with the 'loose sticker in the duct' theory. If only cuz it sound like that and AC performance isn't impacted one bit.

 

here is the prior thread with "sticker in duct" issue


Loud ticking noise with heater on.....

 

I had this. They replaced the steering wheel switches.

 

You can email the video directly to your service manager. I've done that with strange noises which makes it easier. That noise is abnormal no doubt. Definitely not related simply to increased heat from summer...although the AC unit can be loud from outside generally the road noise covers it up from inside.

 

There are several SC's in the Bay Area -- might want to give them a call to see if they can get you in sooner.
