Well, my mystery sound has returned. It doesn't matter what profile, it doesn't matter if my CarPlay is plugged in or not. I don't get it and it's driving me mad.

Mine made a tone when I entered the car, it was driving me nuts. Turned out to be the automatic seat adjustment.

Mine occasionally makes the two toned beep when I start the engine, and then on that same drive happens again randomly 5 or 10 minutes into my drive. I thought it was my phone connecting to something, but no. It's annoying. Really annoying.

Which beep is it?

Without reading back over the entire thread, I have an idea.

Do you have anything sitting on the front seat? If it senses a passenger, then it will bong to remind you to fasten the seat belt. At about 10 mph.

If you don't have anything on the seat, I wonder if the seat sensor might be defective.

Did you turn sound speed limit reminder sound on?
Check and turn it off

Thanks. Definitely not seatbelt alert and definitely not speed limit reminder. That sound comes on even when you enter the vehicle and it isn't started. sounds like a "b-beep" mid tone then higher tone. I thought maybe it was a reminder to plug in my phone into the CarPlay plug since I have a USB3 cord plugged in at all times, but even if I plug my phone in, I get the tone.

Check for notifications. It is the Asterick (*) located in the top right corner of MBUX screen. You can also check for them in your Mecedes Me app.

Thank you for the help everyone.
