Timing belts Megane II CC Coupe 2009

Hello all, an opinion of you would interest me. With my Megane would be changed in May2009 with 100,000 of the timing belts. But also everything on the belt, i.e. Wapu, turning wheels, cam adjuster. Now the car has run 15000 KM, because it is only registered in summer. Of the mileage everything total luxury is now to replace the timing belts and Wapu again, but Renault writes the 5 years ago or 80T KM?. Of course, a belt ages, but the FZG is almost never used for The costs at that time were quite high and this time I would make the change myself, but I just don’t see the necessaryness yet. My colleague from VW said, control cover off and look what it looks like. Would be a possibility. Unfortunately, this is not a free runner, as once my ehmaliger, also 2.0l Avensis, then can drive it is banged and the car stops without cutting the head with valves etc. wide So what do you think about it? Who has experiences about it? As I said. Meanwhile, the car is already 15 years old and so much unnecessary money does not have to be.
