Flywheel

[growler]

Have had my passat 1.9tdi 105 for about a month now and i think i am becoming flywheel obsessed. I have done a search but i cant find a definitive answer so i am hoping someone can help. Firstly does this engine have a dual mass flywheel? Secondly when i put light pressure on the clutch pedal i can feel and hear a slight vibration. The clutch operates ok and doesnt judder. Should i worry? The car has done 110000 miles and is 07 reg.
