When your 2022 BMW X3 displays the P0304 code, the powertrain control module has detected recurring misfires in cylinder 4. Understanding the G01 generation's turbocharged engines enables targeted diagnosis for restoring this luxury compact SUV's driving dynamics.
Understanding P0304 in the 2022 X3 (G01)
The 2022 X3 G01 LCI offers the B48 2.0L turbo four-cylinder and B58 3.0L turbo inline-six depending on trim. Both engines use BMW's sophisticated direct injection and turbocharging. Cylinder 4 location varies—rear on the four-cylinder, fourth position on the six-cylinder.
BMW Turbo Engine Characteristics
Turbocharged engines operate under elevated pressures requiring robust ignition systems. Spark plugs must reliably fire under boost. Direct injection allows carbon accumulation on intake valves—a characteristic BMW owners should monitor. Quality components are essential for maintained performance.
Diagnostic Methodology
Identify your engine configuration. Use BMW-compatible diagnostics for comprehensive data. Locate cylinder 4 based on your engine type. Test ignition coil output against BMW specifications. Inspect spark plug condition. Consider carbon buildup for vehicles with higher mileage.
Repair Implementation
Install BMW-approved spark plugs designed for turbocharged operation. Replace ignition coils showing degraded output. Address carbon accumulation through professional cleaning if indicated. BMW's driving character depends on quality repairs.
