Everything to do with it, I'd say. Takes very little time with inadequate oil pressure to wreck bearings that rely on an oil film.

To fully check an engine after such a loss would involve a major strip-down of engine and turbo, which I guess wasn't their approach...

 

Agreed, sudden oil pressure loss on a car engine can damage parts very quickly indeed, usually the first things to fail are the crankshaft big ends, main bearings and turbo bearings. I lost oil pressure on a Ford 2.0 litre a few years ago due to a rounded oil pump drive shaft when driving at 70mph - I spotted straight away and coasted to a halt but when repaired the engine was never the same again - slight bottom end "tap"

 

I see plenty of cars driven on the motorway with smokey exhausts, not all old diesels accelerating hard, seems owners don't check their oil levels very often and results in the inevitable, expensive detonation of the engine unfortunately.
