Check Engine Light Flashing

A flashing check engine light in your 2023 Mercedes-Benz Maybach GLS typically indicates a severe misfire or an issue that could cause immediate engine damage. When a light flashes, the engine control module is detecting a condition that can allow unburned fuel into the exhaust system, risking catalytic converter damage and much higher repair bills if left untreated. In Tampa, FL, Mercedes-Benz of Tampa urges drivers to stop driving or reduce load and schedule service right away so our technicians can run prioritized diagnostics. Our team uses Mercedes-Benz OEM scanning tools to capture live data, pinpoint misfires, and test ignition, fuel, and turbo systems swiftly.
