Several years ago there were many reports on here of failing Renault Scenic and Megane dashboard problems - sometimes called Cluster.
As I recall - it was reported - the main dealers were charging £400 + to replace them - some enterprising person was charging £100+ for a repair and return service - the issue for some people was how to remove the failing dashboard to send it off. Also the waiting time for it to return.
To find out more use the search box on this page - Scenic Dashboard - Scenic Cluster - Megane Dashboard - Megane
Cluster.
I suspect the costs may have risen.
Good Luck..., April 2016
