When your 2024 Mercedes-Benz GLE displays diagnostic trouble code P0306, the engine control module has detected misfires in cylinder 6. The 2024 GLE offers inline-6 and V8 engine options, all with six or more cylinders, making P0306 a valid code on most variants.
2024 GLE Engine Options
The 2024 Mercedes-Benz GLE features the M256 3.0-liter turbocharged inline-6 with mild hybrid in GLE450 models producing 375 horsepower, and V8 options in AMG variants. The GLE580 uses a 4.0-liter twin-turbo V8. All these engines can legitimately trigger P0306.
Engine-Specific Considerations
On the inline-6, cylinder 6 is at the rear with 48V mild hybrid integration. On V8 models, cylinder 6 is on the passenger bank with twin-turbo complexity. Mercedes STAR diagnostics provide engine-specific analysis.
New Vehicle Warranty
For 2024 models, full warranty coverage applies. Manufacturing defects or premature failures are the primary diagnostic considerations.
