The 2022 Volvo XC60 delivers luxury compact SUV excellence with Volvo's versatile 2.0L four-cylinder platform. When your XC60 displays a P0304 code indicating a cylinder 4 misfire, understanding your configuration helps guide accurate diagnosis.
Understanding P0304 in the XC60
The XC60 uses Volvo's 2.0L four-cylinder in T5 (turbo), T6 (turbo + supercharger), or Recharge (hybrid) configurations. Cylinder 4 is at the rear of the inline-4 engine. The engine control module monitors combustion with precision.
Forced Induction Considerations
All XC60 configurations use forced induction. The turbocharged and supercharged environments create higher combustion pressures that accelerate spark plug wear. Direct injection can contribute to carbon buildup over time.
Diagnostic Approach
Identify your configuration and access the cylinder 4 ignition coil. Inspect spark plug condition. Check for boost leaks in the charge piping. Verify no vacuum leaks exist.
Resolution Process
Replace spark plugs with Volvo specifications. Test ignition coil output. Address any boost system issues. If carbon buildup is suspected, intake valve cleaning may be warranted.
