yep its the dual mass flywheel about 320quid for the parts thats flywheel, clutch and concentric slave cylinder its a full day of a job to do as you have to remove the subframe to get the gearbox out i do one of these at least twice a month sometimes more
i would not use the conversion kits that revert back to a standard flywheel, dmf;s are fitted to higher power diesels to take vibration out of the crankshaft, putting the solid flywheels on puts this vibration back into the crank which will eventually cause the crank to snap (i have known this happen several times usually within 10,000 miles of solid flywheels being fit)
