My experience of an Audi A4 1.9tdi was a dull but totally reliable experience. I bought at 100K and moved on at 200k and the car is still running sweetly a year on, as my brother now has it.
So I guess I can recommend VAG cars but I have never owned an Asian car so cannot give the OP any advice.
Plenty of diesel cars, usually German, are good for very high mileages as long as meticulously maintained. I have no idea if Hyundai's come into that bracket. Audis, Seats, VWs, Skodas should all be good for 200k.
