Check Engine Light Flashing

When the check engine light flashes on your 2020 Ford F-450 Super Duty it signals an active misfire or condition that can damage the catalytic converter or turbocharger. A flashing light is a higher-priority alert than a steady glow; it requires immediate attention. At Bill Estes Ford Brownsburg we perform a rapid but thorough assessment: battery and charging tests first, followed by a full scan of engine and emissions codes. Because heavy-duty diesels have complex aftertreatment and turbo systems, waiting can multiply repair costs and downtime. Our technicians are Ford-certified and trained on diesel diagnostics, so we accurately identify whether the issue is an ignition-related misfire, a fuel-delivery concern, a turbo control fault, or a charging system failure. We keep OEM batteries and components on hand to expedite same-day battery replacements when necessary, and our transparent estimates highlight immediate and long-term savings from using factory parts. Take advantage of current service specials to reduce out-of-pocket cost. For urgent issues, schedule service online or call our service team at Bill Estes Ford Brownsburg — prompt action prevents costly secondary damage and protects vehicle value.
