Diagnostic trouble code P0306 on your 2022 Mercedes-Benz GLE indicates misfires in cylinder 6. The 2022 GLE offers multiple engine options with six or more cylinders, making P0306 a valid code requiring Mercedes-specific diagnostic procedures.
2022 GLE Engine Configuration
The 2022 GLE features the M256 turbocharged inline-6 in GLE450 models, and the M176/M177 twin-turbo V8 in GLE580 and AMG variants. All these engines can legitimately trigger P0306 with cylinder 6 at different locations.
Inline-6 vs V8 Diagnostics
The inline-6 positions cylinder 6 at the rear with mild hybrid integration. V8 models have cylinder 6 on the passenger bank. Both benefit from Mercedes STAR diagnostics for detailed analysis.
Common Causes
Ignition coil wear, spark plug degradation, carbon buildup on intake valves, and fuel injector issues are typical. Turbo system integrity affects V8 misfires.
