Dual Mass Flywheel problems on Skoda's

I am advised that there was a problem affecting the Dual Mass flywheel on older Skoda's/ Volkswagens that caused them to fail with alarming regularity resulting in a costly gearbox replacement and engine rebuild, but that this problem has been largely fixed on the newer models. I am thinking of buying a 2013 (new shape) Skoda Octavia with 92,000 miles on the clock, 6 speed manual 2.0l diesel (elegance spec). One owner form new, (Volkswagen finance rep), so I am guessing most of those miles are motorway driving. Went to see it yesterday and it sounds sound as a bell, no excessive vibration through the clutch pedal when idling or driving. Any comments?
