Looks to me like you have something that is dragging the CAN signal down, that p0472 could be the culprit. Diconnect all of the components listed and check for the 5v reference voltage first. See if you can then clear the d208. If you can clear it, replace the components one by one untill it drops out and resets the fault code. If not,,,, could be a faulty ECU.
