Has anyone else suffered a gearbox failure on there B6 yet?

My 2.0TDI 140 has just limped into the dealer with what they reckon is a flywhel and gearbox failure. It's only 2 years old and done 72k surely that isn't right. The dealer is telling me that it's out of waranty due to the milege and want to charge me £230 just to have a look at it? So much for VW reliability then.
What should my next course of action be and what should I do to get VW to foot some of the cost?

Al help greatfully recieved
Cheers
