I had a lot of issues with prior owner neglect and the m54. Most notably there were numerous vacuum leaks. You might want to check a smoke tester. There's a bunch of old rubber lines and caps back under and behind the intake manifold.
We are on the xoupost.com forum see you there
Great advice from E36: xoutpost is a must to keep the e53 on the road. Guys over there have forgotten more about the x5 than I’ll ever know.
Gird your loins! Mine was a daily for the past 3 years and did great, but it look lots and lots of time and money. To be fair I replace and rebuilt a lot of things that may not have needed it but which I wanted to upgrade, like the rear diff.
