The check engine light flashing on a 2017 BMW 5 Series is an urgent warning that the engine is misfiring or running in a condition that can quickly damage the catalytic converter and other components. A flashing light typically means unburned fuel is entering the exhaust stream, which raises temperatures in the catalytic converter and can lead to a very expensive replacement if not addressed immediately. At Herb Chambers BMW Certified Preowned Medford in Medford, MA, our technicians prioritize flashing-light cases: we perform an immediate diagnostic check, stabilize the engine where possible, and provide a clear estimate for corrective work.
