17705/P1297/004759 - Pressure Drop between Turbo and Throttle Valve (check D.V.!)

Possible Symptoms

  • Power Loss

Possible Causes

  • Leaking hoses and/or pipes between components
  • Check Boost Pressure Control Valve (N249)

Possible Solutions

  • Check hoses and/or pipes between components
  • Check / Replace Boost Pressure Control Valve (N249)
  • Check / clean Throttle Valve, do Throttle Body Alignment

Special Notes

  • Did anyone install an extra (wrong) dump valve?
  • When found in the NAR 2.0T (BPY) check RVUTB: 01-09-03 or 2018919 for updated Crankcase Breather Valve
    • If the breather valve is faulty, full engine vacuum is typically found when removing the oil cap at idle.
