Haven't heard of longevity issues with forced induction BMW or Audi engines. Direct injection has caused problems, but that's unrelated to FI.
After driving a turbo BMW and supercharged Audi, there's no way I'm going back to NA! FI is more fun on public roads, and I don't go to the racetrack.
Generally speaking NA engines outlast FI engines..the reason is the internals on an FI engine wear more quickly because they are operating under many times atmospheric pressure.
