XZBMW  Loud horn at unlocking F30 340i
Hi I have a f30 340i that horn 2x very loud when unlocking.
And that’s not the acoustical confirm (alarm)
Anybody know how to solve / code that annoying horn sound?

Thanks

You should not have any horn when unlocking. Only possible horn should be when locking with engine. Are you setting off OBD alarm?

Is car stock or have there been any hardware or software changes?
