Check Engine Light Flashing

A flashing check engine light on a 2020 Mercedes-Benz GLC-Class Coupe usually signals an active misfire or condition that can quickly harm the catalytic converter or engine internals. Because a flashing light often indicates fuel is entering the exhaust unburned, it requires immediate attention to avoid costly secondary damage. At Park Place Motorcars Dallas, our team prioritizes flashing-light diagnostics and containment — we inspect ignition components, fuel delivery, and emissions systems with OEM-level tools to determine root cause quickly. Choosing dealer service minimizes repeat visits: our technicians follow Mercedes-Benz procedures, fit genuine parts, and log repairs to preserve warranty eligibility. We also provide transparent estimates and explain immediate versus long-term cost implications so you understand value and savings.

Dealer-performed resets are accompanied by documented repairs, genuine Mercedes-Benz parts, and a focus on long-term performance and reliability.
