You mention checking the connections. Was it a specific plug or area where you found the wiring issue?

Yes, it was the connector near the siren. If I remember correctly, there was corrosion on the pins. Have a workshop check it, as it might be more complex, and an alarm reset procedure could be required.

Confirmed wiring issue. Repair completed for 95€. Alarm system is now functioning correctly. Thanks for the insight.

That sounds like the automotive alarm gremlins I had in my Ibiza. I recall similar symptoms with my alarm system. Did you check the connections to the siren itself? They can corrode, like a bad ethernet connection causing network issues.
