Anybody able to help?

Looking for a little advise, I’m getting the following codes. As a little background, I have removed the DPF and cleaned it out in DPF cleaner for 48 hours then flushed through with water for half an hour, filled the Eolys fluid, using diagbox I’ve told the car the fluid is full, there is no fluid in the DPF and that the DPF is new. I also fitted a new battery a few months ago and I’ve tested it with my fluke which shows it’s fine with engine off and the voltage increases with engine on so I think the alternator is also fine. I do occasionally get a code with a bad diesel additive pump. I get a warning come up saying eco deactivated and within a few seconds the service light goes out with the message eco activated. As a side note when I was filling the fluid I tested the pump on a 9v battery and it works fine. I’m thinking maybe wiring to the pump but wondered if anyone had had anything similar. TIA
