My first 4/4 from june 2000 had heated windscreen wich never fails (47000 km).The windscreen of my 4/4 sport has been broken after 2000 km .It was repleaced under waranty by my dealer.They have said that is was not correctly mounted.Too much stress on the bottom of the windscreen due to the leather wich is above the dashboard .They cut off a piece of the leather.
