I assume it is a diesel. I have heard few cases with other brands that fuel injectors were faulty or they had a faulty seal. It caused diesel to leak in to the engine. That caused rising of the oil level when diesel mixed with motor oil.
When I got mine, it was overfilled, to about what your saying. It hesitated a little when taking off and when accelerating from low revs, like a rumble. I took .25l out and got it down to F and its behaved a lot better since then. Its stayed at that level since.I think some workshops are just sloppy when putting oil back in, they will drain out 5l and put 5.2l(what it says in the manual) in and not check the level. Else they are trying to charge you for that extra .2dl of their expensive oil...I'd pump some out if I were you.
I fail to see how the fuel should enter the oil after a failed regeneration, since Hyundai use a system where the fuel is injected directly into the DPF. How do they explain the fuel's way back to the engine oil..?

Is there a difference in FD and GD model regarding DPF regeneration? FD in my country has 20 kkm oil change interval. When I heard the GD model has 30kkm i asked somewhere about the DPF problem of oil dilution and inthat long interval. Someone said to me that its ok because GD model has a direct fuel connection to the dpf, not via more (late) fuel into cylinder injection.
In GD models, extra fuel is injected at the end of the power stroke during regen process. It will not ignite right away, but goes out along the exhaust gas and will burn inside the DPF. However, small amount of that extra fuel will get condensed into the cylinder walls and mix eventually into the engine oil. That happens regardless if the regen process gets finished or not.
