The P0302 diagnostic code on your 2024 BMW 5 Series indicates cylinder 2 is experiencing misfires detected by the engine management system. The all-new G60 generation 5 Series features updated powertrains including mild hybrid systems. Understanding your specific configuration is essential for effective diagnosis.
G60 Generation Powertrains
The 2024 5 Series offers the B48 2.0L turbo in 530i (mild hybrid) and the B58 3.0L turbo in 540i configurations. All inline engines position cylinder 2 second from the timing end. The mild hybrid 48-volt system adds complexity but doesn't directly cause engine misfires.
Direct Injection Considerations
Both engines use high-pressure direct injection susceptible to carbon buildup over time. As a new model year, carbon accumulation isn't expected yet. Manufacturing variations or component defects are more likely causes on new vehicles.
Potential Misfire Causes
New vehicle misfires typically result from component defects—ignition coils, spark plugs, or fuel injectors. Software calibration issues occasionally affect specific cylinders. Assembly irregularities are uncommon but possible.
Symptom Recognition
The executive sedan displays rough idle, vibration, and hesitation with misfires. BMW's refined driving character is compromised when cylinder 2 misfires. Check engine light accompanies the condition.
Warranty Coverage
Your 2024 5 Series is fully covered under BMW's 4-year/50,000-mile warranty. Document symptoms and have dealer diagnosis using BMW ISTA equipment for proper coverage.
