Check Engine Light Service 2019 Mercedes-Benz GLS 450

What do you do when you’re driving along in your Mercedes-Benz GLS 450 and suddenly, a yellow light illuminates on your dash and says "Check Engine". 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. The fear of the unknown (or the price 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 2019 Mercedes-Benz GLS 450 checked as soon as attainable. Ignoring that warning could end up causing major damage to expensive engine components.

When your 2019 Mercedes-Benz GLS 450's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can’t right, a computer turns on your check engine light. This amber or yellow light is often 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 Plaza Motor Company. There are also a number of relatively bargain code readers that are designed for do-it-yourselfers, should you choose that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an professional technical to determine the issue and repair it.

If your check engine light is flashing in your 2019 Mercedes-Benz GLS 450, we extremely suggest not to drive the vehicle and schedule Mercedes-Benz service today. Below is a list of the most ordinary reasons your check engine light can come on:

  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, known as the O2 sensor, measures the amount of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be fewer certain 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 2019 Mercedes-Benz GLS 450's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to choose the proper range of air and fuel that enters the cylinders in your engine. A detrimental O2 sensor can also cause a car to fail an emissions test.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Mercedes-Benz GLS 450 is what determines how much fuel is essential to run your engine efficiently by measuring the amount of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to definitive changes, like altitude. If your Mercedes-Benz GLS 450 is having trouble starting, idling rough or has a precipitous change in the position of the throttle pedal, this could be a sign of a detrimental mass airflow sensor.
  • The battery is low or dead. The battery in your 2019 Mercedes-Benz GLS 450 is every important. 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 genuinely require maintenance. The price of a new one depends on the type of Mercedes-Benz you drive, but check our classic service coupons and specials.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or contrasting item can wreak havoc on your 2019 Mercedes-Benz GLS 450 if it’s not installed subsequently. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prohibit the vehicle from starting. If these issues sound conscious, bring your GLS 450 to Mercedes-Benz and have our company of certified mechanics ensure that your aftermarket items were installed accurately and aren't causing any issue. Getting accessories, notably aftermarket parts and accessories, or using OEM parts initial place might cost a few bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
  • Your 2019 Mercedes-Benz GLS 450 has a vacuum leak. Every Mercedes-Benz GLS 450 has a vacuum system that performs a wide variety of functions. The vacuum system also helps lower 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 dry out and crack, notably if they’re exposed to notable heat or extreme pleasant.
  • One of the most modern and countless cause is that your 2019 Mercedes-Benz GLS 450 gas cap is loose, damaged or missing. The gas cap for your 2019 Mercedes-Benz GLS 450 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 detrimental fuel cap? If your gas cap is old 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 lavish. If your check engine light turns on immediately after you put gas in your 2019 Mercedes-Benz GLS 450, initial thing you should check is to make bold the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • New Spark Plugs or Plug Wires are essential for your 2019 Mercedes-Benz GLS 450. The spark plugs are the part of your engine that ignites the air/fuel range in the combustion chamber of your vehicle. This explosion is what moves the pistons and makes the engine run. The spark plug wires transport the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are detrimental or old, 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, extensive to more lavish repairs.
  • Your catalytic converter is detrimental or going detrimental. The catalytic converter is a part of your 2019 Mercedes-Benz GLS 450’s exhaust system. The catalytic converter's work is to turn the carbon monoxide created by the combustion process into carbon dioxide. A damaged catalytic converter is constantly caused by neglected maintenance, which is why Plaza Motor Company 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 2019 Mercedes-Benz GLS 450 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 contrasting problems from overheating.
