Supplemental conscious reasons for a Check Engine Light are damaged oxygen sensor, a malfunction with the fuel injection system, faulty head gasket, faulty emissions control part, dirty mass airflow sensor, or defective spark plugs to name assorted. No matter what is the root cause of the Check Engine Light, we have the Mercedes-Benz Certified Technicians and the certified service protocol to isolate the root problem and repair it as fundamental to restore factory specifications. When this happens, the Check Engine Light turns off, and you can leave the service center knowing that your Mercedes-Benz issue was fixed.

Every 2015 Mercedes-Benz CLS 400 was designed with a high-technology performance monitoring system with a computer, and a series of sensors positioned strategically throughout the vehicle on its needed systems. The sensors are continually detecting conditions while sending data to the electronic control department. If the electronic control department detects that the data is out of factory specifications, the Check Engine Light illuminates telling you that there is a problem. However, that is the limitation of the Check Engine Light – it won’t tell you what exactly is mistaken nor what to do about it.

Ignoring that warning could end up causing necessary break to expensive engine components.

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 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.

What could cause the check engine light to come on in a 2015 Mercedes-Benz CLS 400?

When your check engine light comes on, this could be as real as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a threatening problem that could cause threatening damage to your engine and come with a extraordinary repair bill. Depending on your make and model, the check engine light will illuminate or blink. A consistent glow mostly means something less threatening but a flashing check engine light illustrates that your vehicle’s engine is in threatening trouble and service is crucial straightaway. If your check engine light is flashing in your 2015 Mercedes-Benz CLS 400, we extremely recommend not to drive the vehicle and schedule Mercedes-Benz service today. Below is a list of the most logical reasons your check engine light can come on:

• The battery is low or dead. The battery in your 2015 Mercedes-Benz CLS 400 is every meaningful. 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 exactly require maintenance. The cost of a new one depends on the type of Mercedes-Benz you drive, but check our modern service coupons and specials.
• Your 2015 Mercedes-Benz CLS 400 has a vacuum leak. Every Mercedes-Benz CLS 400 has a vacuum system that performs a wide variety of functions. The vacuum system also helps lower risky 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 dry out and crack, especially if they’re exposed to dramatic heat or extreme fast.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2015 Mercedes-Benz CLS 400’s exhaust system. The catalytic converter's perform is to turn the carbon monoxide created by the combustion process into carbon dioxide. A damaged catalytic converter is usually 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 fixed, your 2015 Mercedes-Benz CLS 400 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 additional problems from overheating.
• New Spark Plugs or Plug Wires are necessary for your 2015 Mercedes-Benz CLS 400. The spark plugs are the part of your engine that ignites the air/fuel variety 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 long-established, you will experience poor performance and reduced power. In some extreme cases, your engine will have trouble starting or continuing to run. Worn spark plugs and plug wires can cause clogged catalytic converter or damage to ignition coils and O2 sensors, dominant to more expensive repairs.
• Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, accepted as the O2 sensor, measures the sum of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less active 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 damage to your catalytic converter and your 2015 Mercedes-Benz CLS 400's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to find out the right variety 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.
• One of the most prevalent and bountiful cause is that your 2015 Mercedes-Benz CLS 400 gas cap is loose, damaged or missing. The gas cap for your 2015 Mercedes-Benz CLS 400 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 long-established 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 expeditiously after you put gas in your 2015 Mercedes-Benz CLS 400, first thing you should check is to make positive 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 replaced. The mass airflow sensor in your Mercedes-Benz CLS 400 is what determines how much fuel is necessary to run your engine efficiently by measuring the sum 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 CLS 400 is having trouble starting, idling rough or has a fast change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or additional item can wreak havoc on your 2015 Mercedes-Benz CLS 400 if it’s not installed accurately. These aftermarket components and accessories can drain the battery, trigger the check engine light, or even impede the vehicle from starting. If these issues sound common, bring your CLS 400 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 components first place might cost a little bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.

Will the check engine light reset itself?

The check engine light on your 2015 Mercedes-Benz CLS 400 will usually shut itself off if the issue or code that caused it to turn on is fixed. 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. 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. In most cases, your 2015 Mercedes-Benz CLS 400 light will go off after about 20-40 miles. If you drive over that amount and the light is still on, you will need to bring it in to Mercedes-Benz of Chesterfield so the light and code can be double-checked and reset.
