We have a number of Dialog+ systems from 2012 which have had a several cracks appearing in the Valve block level regulation units (type 1). It manifests itself as failing the Blood side pressure tests. Typically around 10K hours. It was so bad that we have had to replace all the type 1 blocks with type 2 units.
You can look at the white manifold on the valve block level regulation units and see cracks on some of the plastic surrounding the blanking ball bearings.
