From what little I know of PD engines, isn't at least part of the problem that they're not all created equal?
I know for example that PD150's are notorious cam issues even as standard, and some variants of the later lower tune 1.9's (PD105?) routinely knock out big-ends or throw rods, again even at standard power. I know that BXE engine codes are one of the later problemsome ones but there's probably others too.
As Matt_Rallye implies above, you can usually get a good idea of reliability looking at availability and pricing of 2nd hand engines - some of the VAG PD engines are cheap because they're broadly reliable and thus there's limited demand for them, whereas others are bordering on unobtainium and priced accordingly.
Of course, it's hardly an issue unique to VAG - PSA 1.6 HDi's are notorious for starving turbos of oil, Renault 2.2DCI's are a joke, and BMW N47 chain failures too.
