+1 Junz comment "one-way valve on feed pipe"

Had mine replaced a few months back on advice from the friend who is a BMW technician, known problem with F30 N20s.

Besides BMW, anyone know where we can get this done?

common fault... some oil feed line gets damaged... my problem was resolved but they could not explain exactly which pipe it was.
