Seeing your check engine light turn on can be stressful, especially when driving a high-performance vehicle. At Malones Automotive Service Department in Marietta, GA, we are pros in diagnosing and repairing check engine light issues for luxury brands like BMW, Audi, Porsche, and many more. 

What Does Your Check Engine Light Mean

The check engine light is part of your vehicle's onboard diagnostics system. It signals that the engine control unit (ECU) has detected an issue within the engine, transmission, or emissions systems. The light can either be steady or flashing. A steady check engine light usually indicates a minor issue, while a check engine flashing light often signals a more severe problem that requires urgent attention.

For example, a Porsche Cayenne may trigger the check engine light due to a failing oxygen sensor, which can impact fuel efficiency and increase emissions. Please never ignore the warning, as it can lead to more significant engine problems and repairs.

How to Clear the Check Engine Light

The best way to clear the check engine light is by addressing the root cause. Disconnecting the battery or using an OBD-II scanner can temporarily reset the light, but the light will return if the underlying problem isn't fixed. It's best to have a qualified mechanic perform professional diagnostics to ensure your vehicle remains safe.
