The 2022 MINI Clubman displaying P0302 with vibration indicates a cylinder 2 misfire in this versatile wagon's turbocharged engine. The Clubman shares its powertrain with other MINI models, allowing well-documented diagnostic procedures.
Clubman Engine Configuration
The 2022 Clubman uses B48 2.0-liter turbocharged engines producing 189-301 horsepower depending on variant (Cooper S or JCW). Cylinder 2 is the second from the front, in a typical transverse mounting position.
Misfire Vibration Pattern
A single-cylinder misfire produces consistent, rhythmic vibration at idle. The frequency matches cylinder 2's firing interval. You may feel pulsing through the seat or steering wheel. Under acceleration, other cylinders mask the power loss, reducing perceived vibration.
Ignition System Testing
The coil-on-plug ignition system places individual coils directly atop spark plugs. Perform a coil swap test—move the cylinder 2 coil to another cylinder. If the misfire follows, the coil has failed. Inspect spark plug condition for wear and deposits.
Fuel Injector Diagnosis
Direct injection operates at high pressures for precise fuel atomization. Injector failures can produce restricted flow, spray pattern issues, or complete failure. MINI diagnostic equipment performs injector balance testing.
Carbon Buildup Factor
Direct injection engines deposit carbon on intake valves. Accumulated carbon affects valve sealing, potentially causing misfires. Borescope inspection through spark plug ports reveals carbon severity.
Repair Costs
Ignition coil replacement costs $150-300 at MINI dealers. Spark plug service runs $200-350. Fuel injector replacement ranges $400-700 per injector. Carbon cleaning service costs $500-1,000.
