I have no evidence to support this, but I'd theorize that some of it has to do with enthusiast owners (porsche) keeping up with recommended maintenance intervals, while budget owners (vw) and ignorant owners (audi) skip maintenance, causing nightmares down the line.

As a personal anecdote: my 2003 VW (1.8T GTI) had 330,000km when I sold it to a friend (it continues to run strong, but not sure the KMs). I did all the work myself and I did it on time. Biggest repair was AC Compressor, the rest was just routine maintenance and a couple $50 sensors. If a CEL came on I addressed it as soon as possible. At the same time, I had a friend with a similar year Jetta TDI which lit on fire around the 290k mark. Every time I was in her car the CEL was on, and I remember driving it home on a road trip once where you'd hold the pedal to the floor the whole way just to keep it at the highway speed limit.
