Back to Generation
1. Loss of Power
  • Symptoms: Noticeable decrease in acceleration and overall engine performance. The vehicle may feel sluggish during acceleration, especially under load or when merging onto highways.
  • Diagnostic Step: Test drive the vehicle to assess acceleration and compare it to performance benchmarks.
2. Increased Engine Noise
  • Symptoms: Unusual whirring, whining, or grinding noises from the engine, particularly when the turbo is engaged.
  • Diagnostic Step: Listen for abnormal sounds during operation and pinpoint their source.
3. Excessive Exhaust Smoke
  • Symptoms: Blue or black smoke coming from the exhaust. Blue smoke indicates oil burning, while black smoke suggests an overly rich fuel mixture.
  • Diagnostic Step: Monitor the exhaust during different engine loads and conditions.
4. Check Engine Light (CEL)
  • Symptoms: The CEL may illuminate due to turbo-related error codes, such as those for boost pressure or air flow.
  • Diagnostic Step: Use an OBD-II scanner to retrieve any trouble codes from the vehicle's computer.
5. Turbo Lag
  • Symptoms: Noticeable delay in power delivery when accelerating, particularly noticeable after a shift in gears.
  • Diagnostic Step: Test the throttle response in various driving conditions to assess lag.
6. Oil Leakage
  • Symptoms: Oil leaking around the turbocharger or associated piping, often leading to oil stains on the driveway or garage floor.
  • Diagnostic Step: Visually inspect the turbocharger and related components for signs of oil seepage.
7. Poor Fuel Economy
  • Symptoms: Increased fuel consumption may occur due to inefficient turbo operation.
  • Diagnostic Step: Monitor fuel consumption over a fixed distance and compare it to manufacturer specifications.
8. Intermittent Boost Pressure
  • Symptoms: Fluctuations in boost pressure, which may be felt as inconsistent power delivery.
  • Diagnostic Step: Use a boost gauge to measure actual boost pressure versus the expected values.
Tools Required:
  • OBD-II Scanner
  • Boost Gauge
  • Basic Hand Tools (sockets, wrenches, screwdrivers)
  • Torque Wrench
  • Flashlight
  • Shop Towels
Step-by-Step Diagnostic Process:

  1. Visual Inspection

    • Check for oil leaks around the turbocharger and associated piping. Look for cracks or damages in the turbo housing.

  2. Check for Codes

    • Use the OBD-II scanner to check for any trouble codes related to the turbocharger. Note the codes for further investigation.

  3. Boost Pressure Testing

    • Install a boost gauge in line with the turbocharger. Start the engine and monitor boost levels during acceleration. Compare actual readings with manufacturer specifications.

  4. Listen for Unusual Noises

    • With the engine running, inspect the turbocharger for abnormal sounds. If necessary, use a mechanic's stethoscope to pinpoint noise sources.

  5. Assess Throttle Response

    • Take the vehicle for a test drive and pay attention to throttle response. Note any lag or unusual behavior during acceleration.
Repair Instructions (if Turbocharger is Faulty)
Tools Required for Repair:
  • Replacement Turbocharger
  • Gaskets and Seals
  • Basic Hand Tools (sockets, wrenches, screwdrivers)
  • Torque Wrench
  • Engine Oil
Step-by-Step Repair Process:

  1. Disconnect Battery

    • Disconnect the negative terminal of the battery to ensure safety during repairs.

  2. Remove Engine Covers

    • If applicable, remove any engine covers obstructing access to the turbocharger.

  3. Disconnect Turbo Piping

    • Detach the intake and exhaust piping connected to the turbocharger. Use appropriate tools to loosen clamps.

  4. Remove Turbocharger

    • Unbolt the turbocharger from its mounting points using a socket set. Carefully remove it, taking note of any gaskets that may need replacement.

  5. Replace Gaskets

    • Install new gaskets and seals on the replacement turbocharger and the corresponding mating surfaces.

  6. Install New Turbocharger

    • Position the new turbocharger in place and bolt it securely. Ensure all bolts are torqued to the manufacturer specifications.

  7. Reconnect Turbo Piping

    • Reattach the intake and exhaust piping. Ensure all clamps are tight to prevent leaks.

  8. Reconnect Battery

    • Reconnect the negative terminal of the battery.

  9. Test Drive

    • Start the engine and allow it to idle. Check for leaks and listen for any abnormal noises. Take the vehicle for a test drive to ensure proper operation.

  10. Clear Codes

    • If any trouble codes were present, clear them using the OBD-II scanner and monitor for any reoccurrences.

By following these steps, you should be able to diagnose and address issues related to a failing turbocharger in a 2012 Volvo XC60 effectively.
