VAG Error Code: 009571
EOBD II Error Code: P2563

Fault Location:
Turbocharger (TC) boost control position sensor (G581) circuit

Possible Cause:
Malfunction Indicator Light (MIL) ON.

Wiring and/or connections faulty.
Turbocharger (TC) boost control position sensor (G581) faulty.
Engine control module (ECM).

Possible Solutions:
Check fuses.
Check wiring and connections.

VAG Error Code: 000175
EOBD II Error Code: P00AF

Fault Location:
Turbocharger (TC)/Supercharger (SC) boost pressure control A - Module performance

Possible Cause:
Malfunction Indicator Light (MIL) ON.
Glow Plug light flashing.
Reduced engine performance.

Wiring.
Engine control module (ECM).

Possible Solutions:
Defective Boost Pressure Control (N75).
Vacuum leak or low vacuum.
VNT sticking or seized.
Charge Pressure Actuator Position Sensor (G581).

Possible Solutions:
Verify Defective Boost Pressure Control (N75) is working to design, use Output Testing.
Verify vacuum lines are good, check engine vacuum at idle.
Test VNT and Charge Pressure Actuator Position Sensor (G581), apply vacuum to VNT and watch MVB 120.4.
Engine off, no vacuum 120.4 should read about 3.5V.
Engine Off, apply 17 Inches of mercury, 120.4 should drop to about .7V.
Engine at idle, 120.4 should read about 7.V.
If 120.4 voltage doesn't alter, VNT may be seized or Charge Pressure Actuator Position Sensor (G581) failed.
