Hmmm, the e39 has a fairly common issue as you describe that is usually brought on by chaffed or broken wires inside the loom that goes from the body of the car into the trunk( sedans) or tailgate (Tourings). See the images below of how when you pull back the corrugated cover on the loom, you'll see broken wires inside as the lid is opened/closed over the course of years that eventually breaks some of the wires. You may want to check (pull back) your X5s wiring looms to insure that you don't have any similar broken wires:
