I haven't had mine checked out, but it buzzes plugged in or not.Have those of you that have had a headlight replaced had the buzzing happen all the time? I haven't heard this buzzing noise in close to a month now, but I don't spend a lot of time near my car when it's parked. Has anyone found a correlation between if the car is plugged in or not when the buzzing happens? My car is going in to the Service Center next Monday for a list of small issues & I'd like to get this addressed at the same time if it is actually a problem. I'd prefer to minimize my number of trips to the SC and I don't want to waste their time.
Sounds like the LED ballast for the headlight. I noticed the buzzing noise right away on the right headlight. We had it replaced and then noticed it coming from the left headlight. It's scheduled to be replaced soon.Hi all,
I also have a refreshed MS70. No noise when I bought it.
After 1 month I had the mentionned problem with the top DRL which didn't work anymore. I reported this to the SEC and they asked me to come in and check it. They needed to replace the left (right if you stand in front of it) headlight completely.
Lately I also noticed that the car is making this computer sound all the time when parked (hot, cold, rainy). In the morning when I park it in the garage of the office it is buzzing and in the evening when I leave he/she is still buzzing. Never thought about the headlight. I will check this as I believe that the noise only came after the replacement now that I think about it.
Maybe it is comming from that new headlight?
The car was in the SEC from wednesday till monday for that replacement.
is there anything wrong with them other than the noise?
I would assume if they are buzzing something is active that shouldn't be and that it will add to the vampire drain that runs your battery down faster. I would thin it would also cause the 12v battery to cycle more cutting its life time down.
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.
