The very best tool to do the diagnostics on a C3 and particularly a diesel from 2002/2003 is Lexia from ebay.

The lexia topic is here

The Lexia tool will give you the correct description for the codes it picks up from the car.

A quick generic description of P1030 is

Powertrain (engine), Manufacturer special code, and then the trail goes cold because you need a manufacturer specific capable tool (like lexia).

Is this the same fault as you posted here? https://citroenc3owners.com/diesel-citro ... t1677.html
There is a reply to it, if its a duplicate, let me know and I will see if they can be merged.

I have read a couple of posts that say the 'lexia' does not work on adiesel C3

Yes, it is the same car. New to all this.

That information is incorrect as I have seen lexia working on a 2002 C3 diesel myself.

What doesn't work are generic OBD2 readers as the early C3 HDi were not fully OBD2 compliant.

No problem, I will flag it up to be merged with your original post so you only have one topic to follow
