Check Engine Light Flashing

A flashing check engine light on a 2014 Volkswagen Jetta signals a severe condition — typically an engine misfire that can damage the catalytic converter or cause additional failures. When that indicator flashes, reduce speed and avoid heavy loads; proceed to Larry H. Miller Volkswagen Lakewood in Lakewood, CO as soon as possible. Our technicians use factory diagnostic tools to capture real-time data and identify whether the root cause is an ignition/fuel system fault, a sensor malfunction, or an electrical issue tied to the battery or charging system. Battery weakness or failing alternators can cause voltage irregularities that produce erratic sensor readings and even intermittent misfires. Addressing a flashing light immediately saves you from higher repair bills and extends engine life. We offer OEM battery replacements, warranty-backed parts, and service financing so you can get necessary repairs completed now and pay later. Check current service specials and schedule service online to prioritize safety and avoid costly downstream damage.
