Common Issues with the AWD System in a 2016 Volvo XC60

The AWD (All-Wheel Drive) system in the 2016 Volvo XC60, part of the first generation (2008-2017), can encounter several common issues. Below are the symptoms, diagnostic steps, required tools, and repair instructions for these problems.

Common Symptoms of AWD Issues

1. Warning Lights:

   • AWD warning light illuminated on the dashboard.
   • Traction control warning light activated.

2. Unusual Noises:

   • Grinding or whining noises coming from the drivetrain.
   • Clunking sounds when accelerating or turning sharply.

3. Poor Traction:

   • Difficulty maintaining traction on wet or slippery surfaces.
   • Noticeable difference in handling during acceleration.

4. Vibration:

   • Vibration felt in the steering wheel or throughout the vehicle, especially during acceleration.

5. Fluid Leaks:

   • Visible fluid leaks under the vehicle, particularly around the transfer case or differential.

Tools Required

• OBD-II Scanner
• Floor jack and jack stands
• Wrench set
• Socket set
• Torque wrench
• Fluid catch pan
• Inspection mirror and flashlight
• Transmission fluid pump (if fluid needs to be added)
• Screwdrivers
• Pliers

Repair Instructions

1. If Warning Lights are Present:

• Clear the codes with the OBD-II scanner and perform a test drive to see if they return. If they do, further diagnosis is required.

2. For Fluid Leaks:

• Identify the source of the leak.
• Replace any faulty seals or gaskets.
• Refill any low fluids using the proper type as specified in the owner’s manual.

3. If Noises are Present:

• Isolate the noise source by performing a stationary rev test (in park) and a rolling test.
• If the noise is from the transfer case, consider replacing it or its internal components.
• For CV joints or driveshaft issues, replace the affected component.

4. For Poor Traction:

• Inspect the tire condition and tread depth; replace tires if necessary.
• Check the AWD coupling for malfunction; if it’s faulty, replace it.

5. If Vibration is Felt:

• Inspect the driveshaft for balance and alignment; replace if bent or damaged.
• Check the wheel bearings and replace them if they are worn or damaged.

6. Fluid Change:

• If fluid is contaminated, drain and refill the transfer case and differentials with new fluid.
• Use the correct type and specifications as outlined in the vehicle’s service manual.

Final Steps

After completing repairs, perform a test drive to ensure that the AWD system is functioning correctly. Recheck fluid levels and ensure there are no leaks. If the problem persists, further investigation may be necessary, potentially involving professional diagnostic equipment or a visit to a certified Volvo technician.
