Volkswagen does not commit to cover clutches beyond six months in its original factory warranty simply because clutch life is dependent on how the car is driven. It is possible to destroy a clutch by burning it out in 15 minutes. Other wearing components such as brake discs and pads will not be covered. But no warranty should ever be allowed to invoke a 'wear and tear' clause after failure of a mechanical component. That would make the warranty truly useless.
