Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hi, the check engine light simply means that an emission related item is malfunctioning. Most of the time the malfunction has no affect on the operation of the engine. As long as your car is running normally you can continue to drive the car and get it to the service center as soon as possible. An independent Mercedes specialist should be able to repair the problem. If the independent shop is not able to figure out the problem you should take the car to the Mercedes dealer.
Let me know if you have any questions.
