Peugeot 301 Alarm Communication Fault

I'm having an issue with my 2020 Peugeot 301 diesel. The system shows a siren communication fault, with an error stored that makes the alarm system not work. It's only done 59051 km, so this seems early. Could the alarm controller be bad, or is it a wiring problem that affects security?

Interesting. I had something similar with my 301. Did you check the connections to the alarm module itself? It's a bit of a pain to get to, but a loose plug could cause that. Did you scan the car for any other fault codes?

Thanks. Were your symptoms the same – a stored error code and a totally dead alarm? Where's the alarm module located in your car?

Yes, the symptoms were exactly as you said. Error code and dead alarm. Honestly, I'd just recommend getting it checked by a professional. It could be a simple fix, like mine was (faulty plug), but you don't want to mess with the security system. Is it worth risking more damage?

Understood, thanks for the confirmation and advice. The diagnostic says it's a defective cable or plug connection. The repair will be about 95€.
