Check Engine Light Flashing

A flashing check engine light on your 2018 BMW ALPINA B6 Gran Coupe xDrive signals a potentially serious condition—often an active misfire that can overheat the catalytic converter or indicate severe electrical faults. Because the ALPINA’s twin-turbo V8 and complex electronics rely on precise voltage and timing, any intermittent misfire or voltage disruption must be diagnosed immediately. At Nalley BMW of Decatur, our factory-trained technicians use BMW OEM diagnostics to capture live data, pinpoint misfires, and inspect the battery and charging systems that commonly influence ignition stability. If the flashing light is related to battery failure or alternator issues, replacing the battery with the correct OEM unit prevents further damage to sensors and catalytic components. We offer clear, written estimates, warranty-backed parts, and same-day battery replacement when parts are available. Take advantage of our current service specials and schedule service online to address a flashing check engine light before it escalates.
