Annoying horn beep!

[MikeHartley]

Hello all.
As per the thread title, my horn has started giving three little horn beeps on my 2011 W212 when the door has been locked.
Anyone got a similar experience or thoughts?
Cheers,
Mike

Isn't there a setting in the convenience menu for silent locking?

It will be in the handbook.

Setting to look for is Acoustic Signal (or something like that) Not the most helpful of names!
