Our local franchise recently cut their ties with Renault and tell me that they can no longer offer full service to their former customers. Renault have protected their franchises with an exclusive protocol, built in to each car's on board computer system, requiring their workshops to have access to dedicated equipment which they have to hand back if they no longer continue dealing with Renault. We run two Renault Clios, which we like but none of our independent garages seem able to do a full diagnostic and reset and our nearest Renault specialist is in another town, 15 miles away.
