17705/P1297/004759 - Pressure Drop between Turbo and Throttle Valve (check D.V.!)
Possible Symptoms
- 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
- Vacuum leak
Possible Solutions
- Check Hoses and Pipes between Components
- Check / Replace Boost Pressure Control Valve (N249)
- Check / Replace Diverter Valve
- Check / Clean Throttle Body
- Perform Throttle Body Alignment (TBA)
- Check for Vacuum leak(s) including PCV system
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.
- When found in the 3B B5/B5.5 Passat 1.8T, check the PCV "bleeder valve" for example part number 06B-103-245
- One way to troubleshoot the problem is to pinch closed the vent hose under the coolant bottle, that attaches to the bleeder valve and see if the idle smooths out.
