You need someone with the citroen/ Peugeot software there are quite a few members on here who may be able to help. Lighty isn't that far from you he may be able to help have a search. Here you go here is his website http://marklightfootltd.co.uk/
Also have a look on French car forum as they have a list of members who have the software and willing to help members out.
