A flashing check engine light in a 2016 BMW Z4 indicates an active misfire or a condition that could cause catalytic converter damage if driven. This is a higher-severity warning than a steady light and requires immediate attention. At Herb Chambers BMW Certified Preowned Medford in Medford, MA, our BMW-trained technicians begin with a targeted diagnostic scan and compression and ignition checks to pinpoint cylinder misfires, fuel delivery issues, or ignition coil failures. Addressing a flashing light quickly avoids the much greater expense of catalytic converter replacement and secondary component failures—so immediate service often saves you money. We use OEM parts and follow BMW service procedures to restore performance and emissions compliance, and we clearly explain warranty implications: any repairs covered under warranty must be performed at a certified dealership to retain coverage. Take advantage of our service specials and ask about service financing to get the work done now and pay over time. To protect your vehicle and avoid escalating costs, schedule service with us for prompt evaluation and repair.
