Clavurion is on a distinguished road
Check basic things on OBD connetor.

Pin 1 Voltage (ignition switched)
Pin 4 Ground
Pin 5 Ground
Pin 7 Diagnostic line to powertrain modules (DME, EGS)
Pin 8 Diagnostic connector to all other modules (via cluster and I-/K-bus)
Pin 16 Voltage (continuous)

When ignition switched to pos. 2 there should be voltage >2 V on diagnostic lines 7 and 8 so communication is possible.
