I have a problem where I can't connect to the ECU via the OBD socket in the glove box. I'm in the process of tracing wiring faults. I have checked the wiring loom behind the battery compartment and someone has done some re-wiring/piecing work. He is re-programming the BSI and is 70% there. He has come up against brick wall. Software asking for a 5 digit after sales access code. We hhave a 4 digit one which we obtained from Citroen for £15 to re-program the key but apparently it isn't that one. Even Citroen don't seem to know. B1aEArK.
