Allarm Alfa Romeo 164

[Biagiocbx]

Evening everyone, I wanted to ask all the owners of alfa 164 with serial alarm (alfa romeo) if this defect has ever happened to you.... I insert the burglar alarm with the remote control, usual 3 flashes and it is activated and the siren emits a beep.. so all good.... but it hasn't done this function for a while and moreover, with the car on and running, sometimes the siren sounds and I'm forced to turn it off with the key... what do you recommend? I changed the internal buffer battery in the siren... thank you Biagio

I have never really used the system in my Q4, so I don't have any ideas, apart from going through the wiring. Maybe something can be found in the manuals on this site.

evening everyone, the alarm works well, all its sensors work, doors, trunk, bonnet....
when driving the siren sometimes emits beeps or sounds constantly....

what can it be?

thank you Biagio

There is a small battery in the alarm unit with the siren, you may want to check that one out. In mine it was completely depleted and started to rust through (the battery I mean), causing issues. Be sure to disable the siren with the key first before you do anything. It's on the right side in the trunk, below the carpet cover.
