How reliable is VOCAL SCW 1?

Both DEKRA / TÜV and insurance companies had tested VOCAL SCW 1 under all possible, even remotely possible circumstances in depth prior to approval.
We use only components produced specially for car electronics, which work reliably in other electronic subassemblies. Siemens for instance produces the relays.
We fix the components using vapour phase soldering, a technology normally only used for aviation or military uses (see our manufacturer).
The switching elements (relays) are doubly activated. Thus failure of one activation signal will have no effect. Each system will be thoroughly check prior to delivery.
