1. Remove the clutch pressure plate including clutch drive plate. Unscrew 6 M8 x 16 pan-head screws crossways in several stages. Remove the thrust
plate, including the drive plate.
NOTE: Make sure not to damage the crankshaft flange when installing and removing the double-mass flywheel (DMF) or Tiptronic drive plate.
