00575 - Intake Manifold Pressure: Control Limit Not Reached

Possible Symptoms

  • Sudden complete loss of Power
  • Reduced Power

Possible Causes

  • Hoses incorrect connected, disconnected, blocked or leaking
  • Pressure Unit for Turbo Charger defective
  • Solenoid Valve for Boost Pressure Control (N75) defective

Possible Solutions

  • Check Hoses
  • Check Pressure Unit for Turbo Charger
  • Check Solenoid Valve for Boost Pressure Control (N75)
  • Check Basic Setting > MVB 011


00575 - Intake Manifold Pressure: Control Limit Exceeded

Possible Symptoms

  • Sudden complete loss of Power
  • Reduced Power
  • Charge Pressure too High

Possible Causes

  • Solenoid Valve for Boost Pressure Control (N75) defective
  • Turbo Charger defective

Possible Solutions

  • Check Solenoid Valve for Boost Pressure Control (N75)
  • Check Basic Setting > MVB 011


00575 - Intake Manifold Pressure: Control Difference

Possible Symptoms

  • Reduced Power

Possible Causes

  • Solenoid Valve for Boost Pressure Control (N75) defective
  • Hoses incorrect connected, disconnected, blocked or leaking
  • In 1Z/AHU engines, stuck/rusted wastegate or actuator.

Possible Solutions

  • Check Solenoid Valve for Boost Pressure Control (N75)
  • Check Hoses
  • In 1Z/AHU engines, clean rust scale off wastegate/actuator to allow lever to move.

Special Notes

It is not uncommon for a TDI to set Implausible Signal Mass Air Flow Sensor (G70) faults and/or Boost Pressure, Intake Manifold Pressure faults when the engine performance is reduced due to excessive restrictions in the intake or exhaust systems. Restricted Catalytic Converters will directly affect turbocharger operation.
