Mystery Noise
Long time lurker. Loving my GLE53 - nice upgrade from the 43. Having one recurring "issue" that the dealer tells me is normal. I hear an intermittent ding or chime that sounds connectivity-related or like something is powering on. Of course every time I try to record it, it doesn't make the sound. I've tried just about every variation of settings I can think of to figure out what is causing it-- turned off the vehicle's WiFi, NFC, Bluetooth, I've tried it with my iPhone plugged into CarPlay vs. not plugged into CarPlay. I have even heard this noise with the car OFF but after having just opened one of the doors. No, it is not a door open chime, seatbelt chime, or parking sensor alert. I have even reset the system to factory settings to see if that would help. On some drives I hear it every few minutes, some drives I won't hear it at all, and other drives I will hear it once or twice. There is no rhyme or reason to it as best I can tell. My dealer tells me it is normal and means the system is "connected." Hard to believe. I just drove a brand new one and did not hear the sound once. I would appreciate any input.
Thanks in advance!

Notification - Check the top right corner of the MBUX to see if there is a * on the hamburger menu. That indicates there is a notification.
Phone is wirelessly charging? I remember seeing that notification on my car, but I don't remember for sure if there is sound with it or not.
The wireless charging path location is also a NFC tag (not sure if it is transmitter or receiver or both, and not sure if it is model dependent). Maybe something triggering it?

Thanks to everyone for the responses. It is not the blindspot monitor, it is not a notification, and I don't use the wireless charging. I will try to reposition the charging mat to see if that has anything to do with it. Regarding NFC, I was wondering if that had anything to do with it. I have turned NFC off in the settings but it did not stop the beeping.
Update: so the mystery beep did it 4 times during my 10 minute drive. Wasn’t the notifications or any of the safety tech. It sounded like the text beep but there was nothing. I remembered When I had a GLE 350 as a loaner last year it did the same thing and they said it was a software update glitch. My guess is that it happened again and the next update should fix it.

If so, maybe the camera needs to be synced.
In Feb, what I did was going online (from the web vs. the app) down the rabbit hole to the Mercedes Me Connect portal (URL: https://www.me.mercedes-benz.com/pas...y-vehicle.html), and added the vehicle there (which eventually synced with the app). Then I "linked" the profile in the car to my login:
^^ that Manage driver profile
Then I linked mine and my wife's, but not my dad's:
Then go out and drive the car a little bit for it to sync over the air. The MBUX screen will show that it has been synced (under Home -> Profile on the top left corner).
