Do not worry, they will be back and you will start to have more problems.
Vacuum leaks and lazy pre-Cat O2 sensors are the most likely culprits. I know the M54 3.0l quite well, the problems are the same across the body styles, however, the X5 has a slightly larger engine compartment so the problems show up a bit later than on the smaller 3 series bodies. More free air space and slightly cooler under hood temps in the E53.
