Hello, i have a fault with my Renault clio. There are 2 lights on the dashboard that renault cant seem to get rid of and are charging me nearly £300 a time to do a diagnostic check on it. The first light is like a graph, looks kind of like a richter scale. The other looks like an engine. It limits the car to driving at about 55mph. Any help would be amazing, but nobody seems to know what is going on.
