When your Mercedes-Benz check engine light goes on, you should be sure to bring it to our Mercedes-Benz dealership in Riverside as soon as possible to determine the cause. Our Mercedes-Benz service experts will perform a check engine light diagnosis to determine if your vehicle requires intensive repairs or if there is a simpler solution.

Common Reasons Your Mercedes-Benz Check Engine Light May Be On:

Gas cap not closed.

If your gas cap is loose, not closed properly or is broken or missing, your check engine light may activate. You can buy a genuine Mercedes-Benz gas cap at our Riverside Mercedes-Benz dealership.

Your car’s oxygen sensor.

Your Mercedes-Benz oxygen sensor monitors your car’s unburned oxygen in its exhaust. As time passes, your sensor gets covered in ash and debris.

Your Mercedes-Benz catalytic converter.

A damaged catalytic converter is a serious issue that needs to be addressed immediately. While it’s likely that there is another fault impacting your car, your engine will suffer if this problem is not fixed soon. You can schedule Mercedes-Benz service at Riverside dealership and let our expert Mercedes-Benz technicians take care of your car.

Spark plugs and wires.

Over time, your spark plugs and wires are going to suffer wear and tear and may malfunction. You can get your vehicle’s spark plugs and wires replaced at Walter’s Mercedes-Benz of Riverside.

Mass airflow sensor.

Your mass airflow sensor provides your car’s computer with information about how much fuel is required based on the amount of air coming into the engine. If there’s an issue, it could cause your car to stall.

Keep your Mercedes-Benz running as it should, by visiting our Riverside Mercedes-Benz dealership for regular maintenance. If your Mercedes-Benz check engine light is on, don’t hesitate to contact Walter’s Mercedes-Benz of Riverside and ask to speak with a member of our service team!
