Movano siren communication fault

I have a Movano too. I had a similar alarm issue. The error memory stored a fault. Did you check the alarm controller?

Thanks. Where is the alarm controller located? I want to check the connections first.

My issue was a faulty connection. But I'd suggest a workshop. The fault location can be tricky.

Thanks for the advice. I had it inspected at a workshop. They found and fixed the bad connection, like you said. Cost me 95€.
