Yes, nonsense quoted from someone who doesn't know any better (the quoted part, not the person that posted).
That was debunked a long time ago.
The "testing" is done with the car whole, the "end of line" check (you can actually do this with VCDS on most models).
Think about it. VAG builds ~10 MILLION cars a year, not counting the significant number of engines they build for marine and industrial use. Do you honestly think they'll pay to do all that on each one??? Porsche doesn't even do that, they randomly pull ONE engine out of about 100 off the line for stand checks.
Quality control being what it is, you can be assured that the vast majority of engines (as well as the rest of the car) are build exactly the same, so jumping through all these hoops is not necessary. If an engine is going to have a major mechanical problem related to assembly, it'll happen quickly after the car is build/sold/driven and will almost certainly be under warranty anyway. It would cost a company as big as Volkswagen LESS to just fix those few that slip through the cracks than it would to test run every engine on every car it assembles.
While I have no issue with UOA, I do think a lot of people get too wound up worrying about them... and the fact that anyone would even pay as much as they cost to have done says that to me. These are mass produced bread and butter cars, they are not exotics, not some hand build racing engines, or anything close. The engine proper is pretty solid, and they have proven to be over and over again. The turbocharger is a weak spot, but that is I feel a victim of aggressive emission control in which case the intentional overfueling and reduced air flow required to crank the EGTs up to regenerate the DPF places extra stresses in the form of heat in play. The poor turbo is just caught in the middle, and I doubt the motor oil itself has anything to do with that.
And FWIW, the CBEA will ALWAYS have much more bearing wear metals in its oil for the first 100k miles than the CJAA does, same as the BHW did over the BEW. And the CBEA has it probably even more because it already left the factory with a gear drive that has a sacrificial coating.
