4595 is smooth running controller cylinder 6. It might be indicative of a faulty fuel injector. Does your bulkhead partitions leak? See this thread

So in terms of your message, E70 35d has only 2 NOX sensors, and you have changed both?
As for 4595, initially we also suspected the injector 6 had problem, but it was running and stopping without any shuddering, does it mean it was really caused by what you suggested "bulkhead partitions leak"?
