My BMW X3 2.5 has high fuel consumption; 15 litres takes me a distance of 100km. What could be the cause of such highs?

The only 2.5-litre X3 was the first-generation petrol model. Its official combined cycle fuel consumption figure is about 11 litres/100km and even when new it would have been difficult to get that, so it doesn't look like you're experiencing particularly awful consumption for that age of car.
Saying that, if you've noticed a deterioration, it could be caused by a crack in the inlet manifold, which is a known issue for that engine.
