W205 under dash trim speaker

[Sparkyme24]

Found this speaker under the under dash trim panel. Close to the accelerator

It doesn’t play any music. What’s this speaker for ? And how do I test it is working?

You sure it doesnt work? - set the fader to fully front and see what happens.

Engine noise over speaker?

I was reading about it. It’s not an audio music speaker but something to do with Warning speaker. Not sure how to test warnings

Pretty sure that's the speaker for the instrument cluster sounds, like indicators and warnings.

Yes, I was thinking that this is some sort of beeper. Especially if it's only on one side of the dash.
