Regarding your issue, with the multiple flashing, the alarm system is trying to tell you that there's a problem with the system. A sensor malfunction, or even the siren could be bad. (Does the siren go off if you trigger the panic function?) The only real way to know is to read the codes in the alarm ECU, you can use the Bimmerlink app for that.
The other thing that could happen, if you bought it used, a previous owner could have coded the beep off, again, for this you'll need another app called Bimmercode and you can code it back. Both apps work with the same Bluetooth dongle.
Good luck!

Hello DonJuan, yes I owned 2 X3s before, I have checked the coding on this vehicle using BMWCarly and the audible locking/unlocking option is active, When I press the panic button the alarm goes off and the horn honks very loud, but I know for sure that the beep when locking/unlocking the vehicle is not related to the horn of the vehicle, so I think I have a damaged alarm sensor/speaker.
