    PCV... positive crankcase ventilation (Crankcase ventilation system - Wikipedia, the free encyclopedia)

    N249... switch over valve for the ECU to operate the DV while under boost

    Most delete the N249, see guide in the stickies and a lot replace the PCV system with a catch can and simpler plumbing.
