It's going to vary depending on A/C use, headlights, temperature, ect.
My previous car would switch to gallons (or liters) per hour when you were sitting still. It would bounce between .5 and .6 gallons/hour IIRC, but that was a 6.0L V8. I would imagine the N54 is considerably less than that with its smaller displacement and the DI.
You could always fill it up, let it idle for a couple of hours, then top it off again if you want a better idea.
