If you drive over that amount and the light is still on, you will need to bring it in to Mercedes-Benz of Fort Pierce so the light and code can be double-checked and reset. In most cases, your Mercedes-Benz light will go off after about 20-40 miles. Likewise, if your catalytic converter is going functional, and you did a lot of stop-and-go driving, that may have turned on the check engine light due to the high usage of the converter. For example, if the cause of your check engine light coming on was a loose gas cap, if it's tightened, the light will turn itself off. The check engine light on your Mercedes-Benz will usually shut itself off if the issue or code that caused it to turn on is fixed. Will the check engine light reset itself?

While this code will tell you the issue that is detected, a true diagnosis still requires an experienced professional to determine the issue and repair it. There are also a number of relatively inexpensive code readers that are designed for do-it-yourselfers, should you choose that route too.
This code is read with an electronic scan tool that is used by our Mercedes-Benz auto repair mechanics at Mercedes-Benz of Fort Pierce. When the light turns on, the ECM stores an engine code or “trouble code” in its memory that identifies as the issue, whether it's a sensor or a failing engine part. This amber or yellow light is typically labeled “check engine” or “service engine soon”, or the light may be nothing more than a picture of an engine, or a picture of the engine with the word “check.” When your Mercedes-Benz 's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can’t correct, a computer turns on your check engine light. Ignoring that warning could end up causing major damage to expensive engine components. But take a deep breath and realize the light coming on doesn’t mean you have to pull the car over to the side of the road and call a tow truck, but it is recommended that you get your Mercedes-Benz checked as soon as possible. The fear of the unknown (or the cost of the unknown) can be just as stressful. If you’re like most Mercedes-Benz owners, your heart sinks a little because you have little idea about what that light is trying to tell you or how you should react. What do you do when you’re driving along in your Mercedes-Benz and suddenly, a yellow light illuminates on your dash and says "Check Engine".
