Tell me where it goes.

My 2009 BMW E91 LCI, which belongs to my wife, needs a new overflow oil line.
Could someone please tell me what it is and how it relates to something I can't seem to locate? Could you please?

By "overflow oil line," do you mean a specific engine?

[ianwh4]

M57N2 and the fuel return line that extends from the injector's upper end.

I believe the M57 goes from 6 to 1 on the HP pump, then from 1 back to pipe, though I haven't played with one in a while. Turn off the intake manifold job so you can see it clearly.

I appreciate it; that is quite useful. Thank you for that.

Above, it is stated.
Almost the same as yours, but older, m57 in my e53.
