2021 BMW M5 Check Engine Light Codes

The most frequent check engine light codes for a 2021 BMW M5 relate to oxygen sensors, misfires, turbocharger boost control, and emissions components. An O2 sensor code can signal poor fuel economy and higher emissions; delaying repair may lead to catalytic converter damage costing significantly more to replace. Misfire codes can indicate spark plug, coil, or injector problems—unresolved misfires can harm catalytic converters and reduce performance. Turbo-related codes can affect boost pressure and throttle response and should be diagnosed promptly to avoid costly turbo repairs. At Herb Chambers BMW Certified Preowned Medford, our BMW-trained technicians interpret these codes in context, perform root-cause testing, and present cost-effective OEM repair options. Choosing dealership service often costs less over time because accurate diagnostics prevent recurring issues and protect resale value.
