2016 BMW M4 Check Engine Light Codes

The most common check engine light codes for a 2016 BMW M4 involve O2/oxygen sensors, misfire detection (P0300–P0306), turbocharger boost sensor faults, and evaporative system issues. Each carries escalating risks and costs if ignored: a faulty O2 sensor reduces fuel efficiency and increases emissions, often costing less to replace early than to repair damage to catalytic systems later; misfires can damage pistons and catalytic converters, leading to expensive repairs; turbo sensor faults can reduce power and, over time, cause turbocharger wear. Nalley BMW of Decatur in Decatur, GA specializes in these diagnostics and offers clear cost-to-fix explanations so you understand immediate repair needs versus long-term savings. Our technicians use BMW-specific diagnostic tools to pinpoint the exact code and recommended OEM parts to maintain performance.
