When your 2024 BMW X5 displays diagnostic trouble code P0306, the engine control module has detected misfires in cylinder 6. The 2024 X5 offers both inline-6 and V8 engine options, all with six or more cylinders, making P0306 a valid diagnostic code.
2024 BMW X5 Engine Options
The 2024 X5 features the B58 3.0-liter turbocharged inline-6 in the xDrive40i producing 375 horsepower, and the S68 4.4-liter twin-turbo V8 in the xDrive50i delivering 523 horsepower. Both engines can legitimately trigger P0306 with different cylinder 6 locations.
Engine-Specific Considerations
On the inline-6, cylinder 6 is at the rear closest to the firewall. On the V8, cylinder 6 is on the passenger bank. Diagnostic access and procedures differ between engines. Both benefit from BMW ISTA diagnostics.
