Check Engine Light Flashing

The check engine light flashing in a 2014 BMW 3 Series 335i indicates a potentially severe condition — often an active misfire that can damage the catalytic converter or compromise engine mechanics. When you see a flashing light, reduce speed, avoid heavy acceleration, and bring the vehicle to Nalley BMW of Decatur in Decatur, GA immediately. Our factory-trained technicians inspect ignition, fuel delivery, and turbo systems using OEM diagnostic procedures to find the root cause quickly. Acting fast saves money: a misfire left unattended can lead to expensive catalytic converter replacement and secondary component failures. At our service center we explain repair options, show the needed OEM parts, and discuss warranty coverage — repairs covered under warranty must be done at a certified dealership to remain valid. We also offer service financing so you can address urgent repairs now and pay over time. Check our current service specials and schedule service online for prompt attention and peace of mind.
