Spec is 8.0 liters, and no, there isn't anywhere oil can be trapped or hidden. I don't know where the "phantom oil" stories come from. But if you really only added a small amount more (8.2L total?), this should not cause an "overfilled" warning. How exactly did you add "slightly over 8 liters, maybe a 1/5 extra of a liter"? Seems like this would require some effort. I pour in 2 gallons and call it good. But anyway:
Assuming you followed the factory procedure and changed the filter first, before draining the sump: It sounds to me like you didn't reset the level sensor after the oil change. Normally this would be done after adding the exact amount (8.0L). If the last reset was done with 8 quarts (not liters), that MIGHT explain why it's showing "overfilled" now.
But anyway, it would probably be a good idea to remove 0.5-1.0 liter and be more careful at the next change. And reset the level sensor per FSM procedure next time.
See attached PDF, step #18, "The following steps are to update the average oil level value."
