What is the 2007-2025 MINI Cooper S Direct Injection Carbon Buildup on Intake Valves?

All turbocharged direct-injection MINI engines (N14, N18, B46/B48) accumulate carbon deposits on intake valves since fuel is injected directly into the cylinder rather than washing over the valves. This reduces airflow and causes rough running. Repairs typically run $400-$800. Severity: medium.

What is the 2007-2020 MINI Cooper S Premature Clutch and Dual-Mass Flywheel Failure?

Manual transmission MINI Cooper S models experience premature clutch and dual-mass flywheel (DMF) failure, often before 60k miles. The DMF springs weaken causing chatter and vibration, and the clutch disc wears prematurely due to the turbo engine's torque characteristics. Repairs typically run $1,200-$2,800. Severity: medium.
