The fear of the unknown (or the cost of the unknown) can be just as stressful. 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 2014 Mercedes-Benz S 550 checked as soon as viable. Ignoring that warning could end up causing considerable damage to expensive engine components.

When your 2014 Mercedes-Benz S 550'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. This amber or yellow light is mostly 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 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 code is read with an electronic scan tool that is used by our Mercedes-Benz auto repair mechanics at Mercedes-Benz of Chesterfield. There are also a number of rather inexpensive code readers that are designed for do-it-yourselfers, should you choose that route too.

What could cause the check engine light to come on in a 2014 Mercedes-Benz S 550?

When your check engine light comes on, this could be as functional as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a strict problem that could cause strict damage to your engine and come with a major repair bill. Depending on your make and model, the check engine light will illuminate or blink. A consistent glow typically means something less strict but a blinking check engine light hints that your vehicle’s engine is in strict trouble and service is essential immediately. If your check engine light is blinking in your 2014 Mercedes-Benz S 550, we particularly recommend not to drive the vehicle and schedule Mercedes-Benz service today. Below is a list of the most sufficient reasons your check engine light can come on:

• Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2014 Mercedes-Benz S 550’s exhaust system. The catalytic converter's function is to turn the carbon monoxide created by the combustion process into carbon dioxide. A damaged catalytic converter is frequently caused by neglected maintenance, which is why Mercedes-Benz of Chesterfield offers a complimentary multi-point inspection with every Mercedes-Benz service. If you have an issue with your catalytic converter and don't get it repaired, your 2014 Mercedes-Benz S 550 will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your car may run at a higher temperature, too, which can cause substitute problems from overheating.
• New Spark Plugs or Plug Wires are crucial for your 2014 Mercedes-Benz S 550. The spark plugs are the part of your engine that ignites the air/fuel collection in the combustion chamber of your vehicle. This explosion is what moves the pistons and makes the engine run. The spark plug wires deliver the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are bad or classic, you will experience poor performance and reduced power. In a small extreme cases, your engine will have trouble starting or continuing to run. Worn spark plugs and plug wires can cause clogged catalytic converter or wear and tear to ignition coils and O2 sensors, dominant to more expensive repairs.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or substitute item can wreak havoc on your 2014 Mercedes-Benz S 550 if it’s not installed accurately. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound commonplace, bring your S 550 to Mercedes-Benz and have our team of certified mechanics ensure that your aftermarket items were installed accurately and aren't causing any issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts first place might cost a small bit more but could save you money from having to get poor work and wear and tear caused by poor installation work corrected.
• One of the most instinctive and frequent cause is that your 2014 Mercedes-Benz S 550 gas cap is loose, damaged or missing. The gas cap for your 2014 Mercedes-Benz S 550 serves multiple purposes. It prevents gas fumes from being released when you aren't driving, it seals the fuel system and helps maintain pressure within the fuel tank. What happens if you have a bad fuel cap? If your gas cap is classic or has a ruptured seal, you can lose fuel through evaporation which will result in more trips to the pump. Luckily, to replace a gas cap isn't expensive. If your check engine light turns on straightaway after you put gas in your 2014 Mercedes-Benz S 550, first thing you should check is to make hopeful the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
• Your mass airflow sensor (known as MAF) needs to be changed. The mass airflow sensor in your Mercedes-Benz S 550 is what determines how much fuel is crucial to run your engine efficiently by measuring the deposit of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to certain changes, like altitude. If your Mercedes-Benz S 550 is having trouble starting, idling rough or has a sudden change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
• The battery is low or dead. The battery in your 2014 Mercedes-Benz S 550 is every routine. Without a car battery, your car won’t start, light up the road ahead, play the radio or charge your phone. Today’s car batteries last much longer than they did a few decades ago, and they don't certainly require maintenance. The cost of a new one depends on the type of Mercedes-Benz you drive, but check our contemporary service coupons and specials.
• Your O2 Sensor (Oxygen Sensor) needs to be changed. The Oxygen sensor, known as the O2 sensor, measures the deposit of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less pragmatic when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A faulty sensor can not only affect your miles per gallon, but it can cause wear and tear to your catalytic converter and your 2014 Mercedes-Benz S 550's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the decent collection of air and fuel that enters the cylinders in your engine. A bad O2 sensor can also cause a car to fail an emissions test.
• Your 2014 Mercedes-Benz S 550 has a vacuum leak. Every Mercedes-Benz S 550 has a vacuum system that performs a wide variety of functions. The vacuum system also helps decrease harmful emissions by routing the fumes as gasoline evaporates through the engine. If you notice that your RPM is high in idle or randomly surges, a vacuum leak could be the cause. Over time, vacuum hoses can arid out and crack, especially if they’re exposed to forceful heat or extreme congenial.
