2025 BMW M8 Gran Coupe Check Engine Light Codes

At Nalley BMW of Decatur in Decatur, GA, we regularly decode the specific trouble codes that illuminate the check engine light on the 2025 BMW M8 Gran Coupe. Common codes include oxygen sensor faults (which reduce fuel efficiency and risk catalytic converter damage), misfire codes (which can indicate ignition or fuel delivery problems and lead to engine damage), and turbocharger or boost control errors (critical for a twin-turbo V8’s performance). Left unaddressed, an oxygen sensor issue can increase emissions and fuel costs, misfires can damage pistons or catalytic converters—costing thousands—and turbo or boost faults can lead to costly replacement of forced-induction components. Our service team uses BMW-approved diagnostics to identify the exact causes and present clear repair options, helping you weigh immediate repairs versus longer-term costs. Because we use OEM parts and manufacturer procedures, repairs performed here often cost less over the vehicle’s life than repeated fixes elsewhere. We also provide service financing, clear warranty guidance (warranty repairs must be performed at a certified dealership), and convenient online booking—schedule service to get prioritized attention.
