Skoda Karoq Alarm System Issue

I'm having a strange issue with my 2023 Skoda Karoq with gasoline engine. The alarm system is completely non-functional, and the error memory shows a siren communication fault. Fault detection points to a defective cable or plug connection. Has anyone experienced this before? It seems like a potential security breach if the alarm disarm isn't working correctly due to this signal problem.

I had a similar issue with my Karoq's alarm system. Was the siren completely dead, or was it just throwing errors? Did you check the alarm controller?

The siren is completely dead. It's throwing an error related to communication fault with the alarm controller. Where exactly did you find the cable issue, and how did you confirm it was the problem?

Yep, same symptoms here. I didn't pinpoint the exact cable, but the workshop confirmed it was the issue. Since it's pointing to a cable problem and the siren is dead, it's likely a broken wire or a loose connection. Probably worth getting it checked by a professional.

Thanks for the help! It was indeed a faulty cable to the siren. Replaced it, and everything is working fine now. Cost me 95€, as predicted by fault detection.
