Volkswagen 2.0 TDI engine problem query

Practical Caravan magazine April 2012, I have a query as a result of the used car test in this month's
 magazine.
 Russ Smith, on page 150, quotes " The 2.0 TDI engines are good, apart from one crucial weakness: the oil pump shaft wears, which causes the engine and the turbo to run dry of oil, destroying both. .....can be prevented by replacing the pump or having it modified before 50,000 miles VW  specialists are well aware of the problem and its cure"
I have a VW Tiguan with a 2.0 TDI engine, which is just approaching the 40,000 mile mark. The above comment re the oil pump is causing me some
concern, as I have just spent over £ 400 having the timing belt and gearbox oil changed as recommended by VW.
Should I be concerned - has anyone any experience of theis "well known problem"
