Hi people, i've just bought a 2003 [03] 1.4 HDI diesel C3 (LX?) & wondering if it is compatible with any of the plug-in diagnostic equipment that is available now & if so, what should i get in order to read it's ECU error codes at least?

Oh, and is there any benefit (apart from the obvious) in having full fuel tank & ought i try to use only certain brands of fuel & if so, which are they please?

Hello nobeard,

The only code reader that does everything and will definitely work on a 2003 Diesel is the Lexia tool.

There is a topic that explains some of the uses of Lexia here.

The only problem with the lexia tool is that its software part can be difficult to install (you will need a laptop with XP or windows 7 to run it, to capture codes and make changes to settings).

There are much cheaper hardware only units, but they don't access all the setting the that the lexia can, they are called OBD2 readers (available here), early Citroen Diesels (usually the ones BEFORE 2004) are not OBD2 compliant! Use Lexia instead
