What years are the relevant cars and is the OBD reader a generic one?

Its not a fault unfortunately, diesel cars didn't have to comply with EOBD until 2004 (petrols were compliant from 2001). Some manufacturers adopted EOBD sooner but generally speaking PSA didn't until they had to.

Generic code readers would never work in my 2002 Xsara HDi either, and in the end I bought a Maxiscan designed specifically for French cars, which worked fine in the Xsara. A Lexia would perhaps have been a better investment though as the Maxiscan was about £150.

Sometimes ago I downloaded an Owner's Manual for Xsara.
To my surprise it was in Spanish or Portuguese

In the fuse definition table "diagnostica" sounds familiar

Then it should be F3 (5A) in cabin fusebox.

To confirm one way or another it'll be best to confirm with a Lexia (pukka Citroen diagnostic tool) that the diagnostic socket is properly working...

It'll be a game of chance if the generic OBD reader will work givern the reasons stated above that OBD on diesels was not compulsory until 2004. Citroen had in the past very much ploughed their own furrow as far as diagniostics were concerned before the law caught up with them...

Bosch EDC15C2 will work with a generic EOBD scanner, though it won't read all of the fault codes.
Seimens SID801 will not work at all.

My Xsara HDi had a Bosch EDC15C2 and it wouldn't communicate with a generic scanner at all

The Maxiscan would work fine with it if the Citroen specific model setting was selected though.
