Ok maybe I am missing something here but how does WVO cause turbo damage, cylinder scruffing, and intake valve build up on a direct injection system. I am new to BD and don't want to run WVO but I don't think the damage to that engine is due to WVO. I think he had poor air filtration that took out his turbo and damaged the piston and cylinder and as for the build up on the intake valve a poorly operating CCV system. I don't really know but that damage doesn't seem to jive with a WVO issue.

For whatever reason, his pistons and cylinders got screwed up. Water in the fuel doing what fuel does not and destroying the pistons, fatty acids or french fries in the fuel damaging the injectors and causing incomplete combustion, building up on the valves and cylinder walls, insufficiently heated fuel contributing to both problems, wrecking his compression, allowing WVO into the crankcase where the turbo draws from (assuming that is how VW's work), the tainted oil not lubing the turbo correctly, thus killing it.

Sounds like this guy hit the trifecta of screwing your engine over.

I don't know what kit that guy used, but I would bet money that it is one of those ones that claims you can dump raw cubbies into it and that it will filter it itself. There's a reason I didn't go with one of those kits.
