Hi, thanks for the swift reply. I'm not sure the car has a fuel filter being petrol and not diesel, I have read on some Peugeot forums that it does not have one. If you have any other suggestions or if you would like to correct me that would be great.

That code usually applies to diesels . If petrol and no in line filter it must have a filter in the tank . part of the tank unit / fuel pump on most cars . which does not normally need replacing . I don't know enough about that car to suggest why it would throw that fault code .
