HPLouis

I was curious. I noticed that there is nothing in the IDrive as far as changes for these fluids. Does anyone change them or plan to? I asked a BMW tech about the coolant becuase I remember that it used to be changed at the 4 year point but now I was told that it was lifetime. I looked at my tranny case and it also said lifetime fluid. I'm guessing that the diff and power settering fluids must be lifetime too.

I'm trying to decide if I should just leave well enough alone and not change these fluids at all. I'm reading different boards and there are compleeing arguments for and against fluid changes.
