Megane III headlight condensation

Hello all. Just picked up my 2012 megane tom tom and must say I really like it, love the car but have a small issue. The passenger side headlights suffers from condensation has anyone else had this and managed to sort the problem?? I have a 4 year renault warranty should this problem be covered under that?

Cheers
