- Malfunction Indicator Light (MIL) ON
- Power Loss
Possible Causes
- Leaking Hoses and/or Pipes between Components
- Boost Pressure Control Valve (N249) faulty
- Diverter Valve faulty
- Throttle Body dirty
Possible Solutions
- Check Hoses and Pipes between Components
- Check / Replace Boost Pressure Control Valve (N249)
- Check / Replace Diverter Valve

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.
