Mines a newer clio and i dunno how much help this'll be but my service light and oil light just randomly came on, i had driven my car around the corner, stopped and checked the oil and it was full even after running, its not a year old and i havent done the service milage so just had to reset it.
Take it to renault and they wil have alook at it, if it needs plugging in best wait until the service to save paying twice or if you smile they may plug it in for nothing before hand.
