Very soft continuous beep

[BLKW202]

hey everyone,

I have a '00 c230 kompressor and recently I've noticed a super low continuous beep when braking and when idle. I ruled out the radio and a/c by turning both off and lowering the windows when driving.
Has anyone had this problem ? Its really annoying (lol)

Could it be an electric problem ? Or a sensor going bad ?

I can't record it, cause my phone will not pick up the sound

Thanks !

Have you checked your rear view mirror?

Sorry, I just had to take a crack at that opportunity.

Seriously though, I have no clue what would beep. A chirp maybe, but not a beep.
