Strange Dashboard Electrical Noise
Hey all,
I just bought a CPO 2019 E300 4Matic. I'm noticing a very annoying high pitched beeping/buzzing noise coming from the dashboard.
It's faint and super high frequency, but verrrry annoying.
I'm bringing it back to the dealership for a look, but has anyone experienced this? Any insight into what it could be?
Thanks.

It needs 2 drops of lubrication + new air filtration cartridge.

PFL205.064 with M276.823 (Oil pump solenoid defeated)
Could it be that the sound is coming from the sensors where the windshield is, I heard it actually get louder when distronic is engaged.

yep!
I think you got it @Egonvdv
The amplifier is actively toasting the center speaker.

It might be the amplifier or some sort of sensor noise.
While it's intermittent, I was able to record it:
