The 2024 Volvo S60 continues with turbocharged 4-cylinder engines exclusively across all powertrains. A P0305 diagnostic trouble code indicating cylinder 5 misfire presents a diagnostic puzzle since this sport sedan only contains a four-cylinder engine.
The P0305 Code Contradiction
Standard OBD-II code P0305 indicates "Cylinder 5 Misfire Detected," but the S60's 2.0-liter engine has cylinders numbered only 1 through 4. This code appearing suggests a diagnostic system anomaly requiring investigation.
2024 S60 Powertrains
All 2024 S60 variants use the 2.0-liter 4-cylinder engine with varying levels of electrification. B5, B6, and Recharge options all use four cylinders only.
Investigating the Anomalous Code
Proper diagnosis requires Volvo VIDA diagnostics to analyze actual misfire counter data for each of the four physical cylinders.
Warranty Coverage
As a 2024 model, software-related diagnostic issues should be addressed under Volvo warranty.
