Check Engine Light Flashing

A flashing check engine light in a 2025 Mercedes-Benz GLE-Class Coupe is a signal that immediate attention is required. Unlike a steady light, a flashing indicator typically means a misfire or a condition that could damage the catalytic converter or other components if driven long-term. At Mercedes-Benz of Lynnfield, our priority is to protect your vehicle and your peace of mind: we use factory-grade scanners and technicians trained specifically on Mercedes-Benz systems to rapidly identify misfires, fuel delivery issues, or ignition faults and provide a clear repair plan. Choosing our dealership for diagnosis often results in immediate and long-term savings—accurate repairs reduce repeat visits and protect fuel economy and the vehicle’s emissions systems. Warranty repairs must be performed at certified dealerships to preserve coverage; our team will explain whether your repair qualifies. Take advantage of current service specials and our service financing options to get needed work completed now and pay over time. For urgent issues, it’s best not to delay—please schedule service online or call Mercedes-Benz of Lynnfield to arrange priority inspection.

2025 Mercedes-Benz GLE-Class Coupe Check Engine Light Codes

The most common check engine codes for a 2025 Mercedes-Benz GLE-Class Coupe include P0300 (random/multiple cylinder misfire), P0171/P0174 (fuel trim or vacuum issues), P0420 (catalyst system efficiency), and sensor-related codes such as P013x for oxygen sensor faults. Ignoring these codes can escalate costs: a misfire left unaddressed can destroy the catalytic converter (a repair that runs far higher than a timely ignition coil replacement), while sensor issues can worsen fuel economy and cause failed emissions inspections. At Mercedes-Benz of Lynnfield we diagnose codes with OEM precision and outline cost-effective repair options. Our certified technicians use genuine Mercedes-Benz parts and follow factory procedures that maximize longevity and maintain vehicle value. We also offer transparent estimates, service financing, and loyalty incentives—check current service specials or schedule appointment to plan your visit.
