My first post and what a great forum.
I spoke with Renault customer service this morning as the wife has just got a 2000 scenic. They said as far as Renault are concerned there is and will be no recall as they only have one report of a "heat related melting incident, No flames" involving a scenic which was not serious and it would be an almost impossible series of events to recreate the problem. Apparently the only reported damadge was minor. They assured me that there is a minimal risk but if I wanted to take my vehicle into a Renault dealer they willl check it out free of charge and if necessary replace anything that looks hazardous
So I feel totally reassured now
