Check Engine Light Flashing

A flashing check engine light on your 2012 BMW X5 M is a serious warning that indicates a potential misfire or condition that could damage the catalytic converter or other drivetrain components if driven without inspection. When the light flashes, it usually means the engine is not running correctly under certain loads — this can cause unburned fuel to enter the exhaust and overheat the catalytic converter, leading to expensive repairs. At Herb Chambers BMW Certified Preowned Medford in Medford, MA, our factory-trained technicians prioritize safety and long-term value. We perform immediate, OEM-compliant diagnostics to isolate misfires, ignition or fuel delivery faults, and associated issues. Acting quickly preserves performance, maintains fuel economy, and can prevent cascading damage that drives costs higher over time. We encourage customers to take advantage of current service specials and our transparent estimates. If financing would help, we offer service financing so you can get the necessary repairs now and pay later. To avoid further damage and secure a quick, accurate repair by certified technicians, please schedule service with our Medford service team today; our experts will explain recommended repairs, warranty coverage, and long-term benefits of OEM parts and factory procedures.
