Check Engine Light Flashing

The check engine light flashing on a 2014 Volkswagen Passat is an urgent warning: it often indicates a severe misfire that can damage the catalytic converter or compromise safety. A flashing light means the engine is running poorly enough to create unburned fuel in the exhaust stream, which risks overheating emission components and increasing repair costs if delayed. At Larry H. Miller Volkswagen Lakewood in Lakewood, CO, our factory-trained technicians prioritize immediate assessments when a light is flashing. We use OEM diagnostic equipment to identify misfires, ignition faults, and fuel system issues and provide a clear timeline and cost estimate so you can decide confidently. Our service advisors will explain how prompt repair at our dealership can prevent larger bills later, preserve warranty eligibility, and maintain your Passat’s performance. Take advantage of current service specials and ask about service financing if you need to schedule service now; we’ll get you back on the road safely with certified repairs and genuine parts.

Resetting the check engine light on a 2014 Volkswagen Passat can be as simple as addressing a loose gas cap, but the best practice is a professional diagnostic reset after the root issue is repaired. At Larry H. Miller Volkswagen Lakewood we don’t just clear codes — we confirm the underlying problem, repair it with OEM parts, and reset the system so the fix is permanent. That approach protects you from recurring issues and preserves warranty coverage; remember, warranty repairs must be done at a certified dealership to remain valid.
