Every time your car goes to a Renault Dealer ask them to carry out an ICM check on Renault Net, Renault are pretty good at ensuring that known faults in large numbers of cars are rectified, every month the dealer gets technical notes, nt notes and a dialogys update. So if anything needs doing they should do it for you but they can only repair what has come up in the ICM check and nothing else unless you state that you have a fault, which will then be a warranty claim.
