What could cause the check engine light to come on in a 2012 Mercedes-Benz GL 450?

When your check engine light comes on, this could be as easy as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a precarious problem that could cause precarious break to your engine and come with a colossal repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow typically means something less precarious but a twinkling check engine light indicates that your vehicle’s engine is in precarious trouble and service is needed straightaway. If your check engine light is twinkling in your 2012 Mercedes-Benz GL 450, we highly recommend not to drive the car and schedule Mercedes-Benz service at this moment. Below is a list of the most innate reasons your check engine light can come on:

  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Mercedes-Benz GL 450 is what determines how much fuel is needed 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 decisive changes, like altitude. If your Mercedes-Benz GL 450 is having trouble starting, idling rough or has a abrupt change in the position of the throttle pedal, this could be a sign of a threatening mass airflow sensor.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, simple 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 automobile will be less functional 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 2012 Mercedes-Benz GL 450's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to choose the honorable mixture of air and fuel that enters the cylinders in your engine. A threatening O2 sensor can also cause a car to fail an emissions test.
  • Your catalytic converter is threatening or going threatening. The catalytic converter is a part of your 2012 Mercedes-Benz GL 450’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 usually 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 2012 Mercedes-Benz GL 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 other problems from overheating.
  • New Spark Plugs or Plug Wires are needed for your 2012 Mercedes-Benz GL 450. The spark plugs are the part of your engine that ignites the air/fuel mixture in the combustion chamber of your automobile. 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 threatening 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 wear and tear to ignition coils and O2 sensors, major to more expensive repairs.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak havoc on your 2012 Mercedes-Benz GL 450 if it’s not installed appropriately. These aftermarket parts and accessories can discard the battery, trigger the check engine light, or even prohibit the automobile from starting. If these issues sound admitted, deliver your GL 450 to Mercedes-Benz and have our team of certified mechanics ensure that your aftermarket items were installed perfectly and aren't causing any issue. Getting accessories, immensely aftermarket parts and accessories, or using OEM parts first place might cost a little bit more but could save you money from having to get poor work and wear and tear caused by poor installation work corrected.
  • Your 2012 Mercedes-Benz GL 450 has a vacuum leak. Every Mercedes-Benz GL 450 has a vacuum system that performs a wide mixture of functions. The vacuum system also helps lower threatening 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 dehydrated out and crack, immensely if they’re exposed to notable heat or extreme precipitous.
  • The battery is low or dead. The battery in your 2012 Mercedes-Benz GL 450 is every lanky. 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 really require maintenance. The price of a new one depends on the type of Mercedes-Benz you drive, but check our current service coupons and specials.
  • One of the most commonplace and innumerable cause is that your 2012 Mercedes-Benz GL 450 gas cap is loose, damaged or missing. The gas cap for your 2012 Mercedes-Benz GL 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 threatening 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 expensive. If your check engine light turns on urgently after you put gas in your 2012 Mercedes-Benz GL 450, first 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.
