Check Engine Light Flashing

A flashing check engine light on a 2015 Mercedes-Benz SL-Class typically indicates a severe misfire or condition that risks immediate engine or catalytic converter damage. A flashing indicator requires prompt attention; continued driving can cause expensive downstream failures that far exceed the initial diagnostic.
