Hi, I have a C8 o4 plate 2.0l HDI whist on holiday in Wales with wife and kids the car stopped and a immobiliser fault came up on the display, the RAC guy tested all the fuses, all good. We were towed to a garage wereb the guy said he will have a look at it so far no joy. Does anyone out there in Citroen land know what could possibly be wrong. Can it be reset or what. Please help I am at my wits end.
