NV alarm siren communication fault

Hey there. I've got an NV too, and that siren thing sounds familiar. Did the error code point to anything specific, or did it just say 'siren communication fault'? Wondering if it's a common problem or something unique to our vans.

The error code was rather generic, only indicating a siren communication fault. It didn't specify a particular location or component within the alarm system. Did you experience the same lack of detail when you encountered a similar issue?

Yep, pretty much the same. No specifics, just the siren fault. Honestly, after fiddling around for a bit, I just took it to a workshop. Saved me a bunch of headaches. Might be the easiest route for you too.

I appreciate your input and sharing your experience. Given the potential complexity and my limited expertise, I believe a visit to a trusted workshop is indeed the most prudent course of action. I have already made an appointment, and they quoted me around 95€ for the repair, hopefully, it won't be more than that.
