first of all hope this is in the most appropriate place on the forum. When your Renault visits a Renault main dealer for a service the cars onboard computer is scanned and checked for any fault codes and software upgrades. But a check is just that a check. So say a software upgrade is available for your car is the upgrade downloaded anyway free of charge and how much difference does it really make.
