Ranger, my X5 has adjustable height suspension. It does this via airbags struts. The dealership wanted to try all these other options via trial and error while I pay for each error.

I finally took the car into a bmw mechanic, they replaced the airbag strut on the passenger side which has a very slow leak. It caused the car to lean to one side over night until I turned the car on, then it tried to level itself when I turned the car on but it never leveled completely. After it was replaced now the car never leans.
