As far as I am aware, and dont take this as set in stone, Renault do not operate such a scheme. However, if a part becomes "back ordered" with a V.O.R (vehicle off road) situation, a courtesy car can be claimed via the parts department of your local Renault dealer. Ask for details if it is a TRUE V.O.R.
To qualify, the vehicle MUST BE OFF THE ROAD AND NOT DRIVEABLE!
So, a faulty ashtray would not qualify!
Hope that helps!
