Is ambient light buzzing resolved?

[EarlyAdopter]

When you say no buzzing here, please make sure it is dark, you are in night mode, and your screen brightness is way down (10% of less in my case).
Buzzing galore in that situation...

Just ran down to double check. Confirmed - no buzzing under those conditions. I can slide up and down from 100% to 0% and back and forth in night mode and hear no buzzing.

Thanks for the feedback everyone. It is looking like cars with VINs above a certain number were built with a fix while those below are still waiting resolution. Perhaps more people will chime in to confirm or refute the hypothesis further. If the hypothesis holds perhaps we can get an idea around what VIN the fix was implemented in new builds.

Did you make sure the ambient lights were on? Even though you turn the screen manually to night mode, the headlights must be on for the ambient lights to come on.

Hey Ddruz, thanks for all the work!

My car has the buzz, P001766.

I was told the fix required the main 17" screen to be replaced. I'm vin #513 and the Columbus service center has it on order to be replaced. I will report back after repair is scheduled and completed. p

No worries as Tesla is standing behind their Model S.

Wow. Screen replacements planned/required on the first several thousand VIN's? That sounds kind of expensive.

 

[ShortArc]

Still buzzing.
No way this will be a SW fix.
Screen or LED driver/power electronics replacement sounds much more plausible.

I don't care if there is a buzz. I changed the settings and eliminated it long ago. I doubt I or most owners will want to replace the screen to eliminate the buzz.
Every time you fix one thing, you can hurt other things.
Only fix if you are bothered.

Re-checked mine last night. I could see the ambients and dash lights go up and down in unison with the slider. Absolutely no buzzing or noise that I can hear with the dash in either day or night mode anywhere from 0 to 100%.

Yes, of course. I watched the ambient lighting rev up and down in brightness as I moved the slider for dash illumination level. No buzzing at all.

Just spent a little while testing this on my car (P6649, built in early March). Happy to report no buzzing whatsoever, regardless of display brightness.

I never had the buzzing on my car (built late Dec 2012)

No.

I believe you mentioned already having a screen replacement, no? It was speculated earlier in this thread that the culprit is the 17" display.

Yes, mine was replaced.

I just took mine in for annual service and I mentioned the ambient light buzzing as an ongoing issue. They told me that it would be addressed in a software update - nothing about replacing the 17" which is what I was expecting.

Which version are you on?

 

[apacheguy]

Which version are you on?

Currently the .44 release of 4.5. We'll see if the service techs upgrade it.

 

[Jrhodesmd]

Not fixed. Is a ballast issue in earlier cars. Sure hope it is fixed in software soon.

I have a P85+ loaner car right now (VIN # 11,264) and it doesn't appear to have the ambient light buzzing issue. The fan is on, so maybe it's covering up the sound (It's running 4.5 software version .44). I'll check it again tonight, but compared to my Sig (VIN 532), the buzzing seems much reduced, if not eliminated. My Sig still has it, but I told service about it when I took it in this week and they are seeing what they can do.
