Back to Generation

1. Loss of Power

  • Description: The vehicle may feel sluggish, especially during acceleration. You may notice that the turbo does not engage as it should.
  • Cause: A failing turbo can result in insufficient boost pressure, leading to a decrease in engine performance.

2. Excessive Exhaust Smoke

  • Description: There may be noticeable blue or black smoke coming from the exhaust.
    • Blue Smoke: Indicates oil is leaking into the turbocharger and combusting.
    • Black Smoke: Indicates an overly rich fuel mixture, possibly caused by a malfunctioning turbo.

3. Unusual Noise

  • Description: You might hear a whining, grinding, or hissing noise coming from the engine bay, particularly when accelerating.
  • Cause: Worn bearings or damage to the turbine can create these sounds.

4. Check Engine Light

  • Description: The check engine light may illuminate on your dashboard.
  • Cause: The vehicle’s onboard diagnostics may detect abnormal readings related to boost pressure or other engine parameters associated with the turbocharger.

5. Poor Fuel Economy

  • Description: A noticeable drop in fuel efficiency can occur.
  • Cause: A malfunctioning turbo can lead to an improper air-fuel mixture, causing the engine to consume more fuel.

6. Boost Pressure Issues

  • Description: The turbo gauge (if equipped) may show lower than normal boost levels.
  • Cause: A failing wastegate or a boost leak can affect the pressure generated by the turbo.

Step 1: Visual Inspection

  • Tools Required: Flashlight, inspection mirror.
  • Instructions:
    1. Open the hood and visually inspect the turbocharger and surrounding components for any signs of oil leaks or damage.
    2. Check for loose or damaged hoses that could indicate a boost leak.

Step 2: Scan for Diagnostic Trouble Codes (DTC)

  • Tools Required: OBD-II scanner.
  • Instructions:
    1. Connect the OBD-II scanner to the vehicle's diagnostic port.
    2. Check for any stored trouble codes related to the turbocharger or related systems (e.g., P0299 - Turbo/Supercharger "A" Underboost Condition).

Step 3: Boost Pressure Testing

  • Tools Required: Boost pressure gauge, vacuum pump.
  • Instructions:
    1. If possible, connect a boost pressure gauge to the intake manifold.
    2. Start the engine and monitor the boost pressure while accelerating. Compare the readings to the vehicle’s specifications.

Step 4: Sound Check

  • Tools Required: Mechanic's stethoscope (optional).
  • Instructions:
    1. Listen carefully to the turbocharger while the engine is running.
    2. Identify any unusual sounds such as whining or grinding that could indicate internal damage.

Step 5: Inspect Oil Supply

  • Tools Required: Oil pressure gauge, wrench set.
  • Instructions:
    1. Check the oil level and condition in the engine. Low or dirty oil can affect turbo performance.
    2. Inspect the oil feed line to the turbo for clogs or damage.
Repair Instructions

Step 1: Addressing Oil Leaks

  • If oil leaks are found, replace any damaged seals or gaskets. Use appropriate torque specifications when reassembling.

Step 2: Turbocharger Replacement

  • If diagnostics confirm a failing turbocharger:
    1. Tools Required: Socket set, wrench set, torque wrench, gasket scraper.
    2. Instructions:
      • Disconnect the battery and remove any engine covers if necessary.
      • Remove the intake and exhaust pipes connected to the turbo.
      • Disconnect the oil feed and return lines.
      • Unbolt the turbocharger from its mounting points.
      • Install the new turbocharger by reversing the removal steps, ensuring all gaskets and seals are replaced.

Step 3: Clear Codes and Test Drive

  • After repairs, clear any DTCs using the OBD-II scanner.
  • Take the vehicle for a test drive to ensure that the turbocharger is functioning properly and that no warning lights reappear.
Conclusion

If you experience any of the symptoms associated with a failing turbocharger in your 2009 Volvo XC60, follow the diagnostic steps outlined above. If the issue is confirmed, consider replacing the turbocharger to restore optimal performance. Always refer to the specific service manual for torque specifications and additional details pertinent to your vehicle model.
