Skoda India — skoda superb instrument cluster backlight not working

I am facing this issue since past 1 year as my car skoda superb instrument cluster led's are not functioning properly. At the service station they said they will replace the instrument cluster which costs around 100k. I have faced numerous issues in this car but i thought it was wear and tear with every car though in this car wear and tear is quite more than others. But i don't think this instrument cluster issue is due to wear and tear. I have owned many cars over last 10 years and i haven't faced problems of instrument lights ever. Why skoda has all the issues? I want this to be replaced in goodwill warranty which skoda is refusing
