OBD2 will talk to a c3 hdi 8v 2005.

I don't know if OBD2 will give enough information to diagnose the 'eco mode' problem you have as 'eco mode' is a citroen specific feature. Its worth a try as OBD2 readers are quite cheap.

obd2 reader on amazon (here)

The tool you will probably end up needing is lexia (info here) but the OBD2 tool above may just be enough to diagnose the engine light. If you get the engine started after clearing or fixing the engine light (MIL) then eco-mode will disappear.
