A clutch and flywheel could certainly be needed at 80k, as they depend on how the car has been driven.
EGR valve could also need a good clean, and the manifold is probably quite clogged as well, but as before depends largely on how it has been driven.
It is quite a moderate mileage for it's age, which sort of suggests that it has done shorter journeys, and shorter journeys sre not good for modern Diesels.
The turbo I wouldn't expect to need replacing, unless the car has been run low on oil or has skipped services.
However I did read somewhere that a clogged DPF on some cars can cause enough backpressure to stop a turbo spinning properly, and that can lead to the turbo bearings failing as they will overheat and not be lubricated properly.
You will never be cool driving a Vauxhall.
