2015 BMW M6 Gran Coupe Check Engine Light Codes

The 2015 BMW M6 Gran Coupe uses advanced onboard diagnostics that record specific trouble codes for engine, emissions, and turbocharger systems. In Decatur, Nalley BMW of Decatur sees frequent codes related to oxygen sensors (P0130–P0167 range), misfires (P0300–P0308), and boost control or wastegate solenoid faults specific to high-performance twin-turbo engines. Left unchecked, an oxygen sensor failure can reduce fuel efficiency and damage the catalytic converter, leading to repair costs that escalate quickly; a bad sensor repaired early prevents a catalytic converter replacement that can cost several thousand dollars. Misfires can cause piston or catalytic damage if ignored; diagnosing and fixing ignition or fuel delivery issues at the dealership preserves engine life and performance. Our certified BMW technicians use OEM tools to pull exact codes, provide transparent estimates, and explain both the short-term repair cost and the downstream savings of timely service. Take advantage of Nalley BMW of Decatur’s convenient scheduling and tailored service specials to minimize both expense and interruption to your driving.
