All clutches wear out.
Even the clutch in a Dualogic will wear.
It is basically the standard dry manual clutch and almost standard gearbox but instead of being operated by a simple manually operated master cylinder with slave, your foot and a few cables, rods to the gear lever and your hand, it's all operated for you by hydraulics, servos, valves, sensors and powered by a pump with an electronic brain.
They both suffer similar sort of problems, worn out clutch, leaking hydraulics, perhaps even a worn input shaft bearing on an older car.
The difference is getting these repaired.
The manual is easy, nearly any garage can swap a clutch or master or slave cylinder or even fit a recon gearbox.
The Dualogic is a bit different, you'll need someone who knows how and they are few and far between plus the parts are expensive.
A manual master or slave cylinder is peanuts compared to the complicated hydraulic that operate the Dualogic.
