Welcome to the forum!
As Krafty said, there have been a lot of issues with clutches. They put these Dual Mass Flywheels in and because the clutch face is thinner, the flywheel doesn't dissipate friction-generated heat as quickly as it should and causes the clutch to overheat, which in turn destroys it and the pressure plate's springs. The entire thing has to be replaced.
That could be what your problem is. Other people have reported an issue with the thrust bearing or lifter - it may be cracked or damaged.
Either way, the bell housing's going to have to be cracked open so it can be inspected.
