00575

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.
