Regular inspections can help catch any wear and tear before it turns into a costly repair.
Other Key Components
Beyond the engine, transmission, and suspension, the M340i is equipped with various electronic systems that enhance reliability. The infotainment system, while sometimes criticized for its complexity, generally operates well without major issues.
