The P0302 diagnostic code on your 2024 Mercedes-Benz GLE indicates cylinder 2 is experiencing misfires detected by the engine control module. The W167 GLE offers multiple powertrains including the M256 3.0L turbo inline-6 and the M176 4.0L twin-turbo V8. Understanding your specific configuration is essential for effective diagnosis.
GLE Powertrain Options
The GLE450 uses the M256 3.0L turbo inline-6 producing 375 horsepower with EQ Boost mild hybrid. The GLE580 features the M176 4.0L twin-turbo V8 producing 483 horsepower. Plug-in hybrid versions combine inline-6 with electric motors. Cylinder 2 location varies by engine configuration.
M256 Inline-6 Specifics
Cylinder 2 is second from the timing end on the inline-6. Direct injection provides efficient fuel delivery. The mild hybrid ISG assists with starting and acceleration. As a newer model, defects rather than wear are more likely misfire causes.
M176 V8 Considerations
The V8's cylinder 2 is on the passenger bank. Twin-turbo configuration creates high underhood temperatures. Direct injection can develop carbon over time. The powerful V8 stresses ignition components.
Symptom Recognition
The mid-size SUV displays rough idle, vibration, and hesitation with misfires. Mercedes-Benz's refined driving character is compromised. Check engine light accompanies the condition.
