Seat Leon Hybrid Alarm Issues

Has anyone else had issues with their alarm? My 2022 Seat Leon hybrid keeps throwing a siren communication fault error. Now the alarm doesn't work. Could this really be just a loose wire? The garage mentioned a potential security breach, which is a bit concerning.

A 2022 Seat Leon hybrid experienced a consistent siren communication fault error, rendering the alarm non-functional. The issue was suspected to be a loose wire or faulty connection. After a garage inspection, a defective connector on the siren was identified and repaired, resolving the problem.

Sounds like a pain. Is the error message consistent, or does it come and go? A faulty connection would make sense with those symptoms.

Consistent error. So, you think it's likely just a wiring issue? Is there any chance a full alarm reset could fix it, or am I wasting my time?

If the error is consistent, an alarm reset probably won’t help. A wiring issue is possible. Given the fault detection points to a defective connection, and the alarm system is non-functional, it's best to get it checked properly. Probably best to get it to a workshop.

Thanks for the input. The local garage found a dodgy connector on the siren. 95€ later, the alarm is working again. What a relief!
