2020 BMW 8 Series Gran Coupe Check Engine Light Codes

Check engine light codes for the 2020 BMW 8 Series Gran Coupe commonly point to faults such as misfire codes (P0300-P0306), oxygen sensor or catalyst efficiency codes (P0130-P0175), and turbocharger or boost-related codes in turbocharged engines. Each code has cost implications: leaving a misfire untreated can ruin the catalytic converter (a high replacement cost), while ignored sensor faults can reduce fuel economy and increase emissions, and boost leaks or turbo faults can lead to larger drivetrain repairs. At Nalley BMW of Decatur we translate codes into actionable repair plans with transparent estimates and a focus on long-term savings. Our factory-trained technicians use OEM parts and software updates when needed, which often costs less over time compared with repeated, partial fixes. We also honor warranty requirements — any warranty-covered repairs must be performed at certified dealerships to preserve coverage — and we guide you through coverage eligibility.
