Master siren communication fault

Hi, I've got a 2021 Renault Master, electric engine, with about 47k km on the clock. I'm getting a 'siren communication fault' error stored. The alarm system isn't working either. I'm guessing it's a cable or plug issue. Anyone else had this?

Yeah, I had a similar issue with my 2018 Opel Corsa. Alarm was acting up. Have you checked the alarm fuse? Might be a simple fix.

I haven't checked the fuses yet, I was planning on doing that next. Did the fuse fix it for you, or was it something else?

Unfortunately not, I took it to a shop. It turned out to be a wiring issue with the siren itself. If checking the fuses doesn't work, I'd suggest taking it to someone. Mine was throwing errors too.

Thanks for the info. I've checked the fuse and it's not that. I will book it in with a mechanic. They quoted me 95€ for the repair which sounds reasonable.
