What could cause the check engine light to come on in a 2016 Mercedes-Benz GL 450?

When your check engine light comes on, this could be as simple as tightening or replacing your gas cap. Also, the check engine light could also be a warning of a serious problem that could cause serious damage to your engine and come with a hefty and pricey repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady and continuous glow usually means something less serious but a flashing check engine light reveals that your vehicle’s engine is in serious trouble and useful service is necessary promptly. If your check engine light is flashing in your 2016 Mercedes-Benz GL 450, we very endorse not to drive the vehicle and schedule Mercedes-Benz service today. Below is a list of the most common 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 more instantly and your car will be less efficient when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A defective sensor can not only affect your miles per gallon, but it can cause significant damage to your catalytic converter and your 2016 Mercedes-Benz GL 450's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the explicitly correct combination of air and fuel that enters the cylinders in your engine. A defective O2 sensor can likewise cause a vehicle to fail an emissions test.
  • Your 2016 Mercedes-Benz GL 450 has a vacuum leak. Each Mercedes-Benz GL 450 has a vacuum system that performs a wide variety of functions. The vacuum system likewise helps lower unhealthy 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, particularly if they’re exposed to intense heat or extreme cold.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2016 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 broken catalytic converter is normally caused by constantly neglected maintenance, which is why Park Place offers a complimentary multi-point inspection with each Mercedes-Benz service. If you have an issue with your catalytic converter and don't get it repaired, your 2016 Mercedes-Benz GL 450 will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your vehicle may run at a higher temperature, too, which can cause other dangerous problems from overheating.
  • 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 necessary 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 certain changes, like altitude. If your Mercedes-Benz GL 450 is having trouble starting, idling rough or has a sudden speedy change in the position of the throttle pedal, this could be a essential sign of a defective mass airflow sensor.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your 2016 Mercedes-Benz GL 450 if it’s not installed accurately. These aftermarket components and accessories can drain the battery, trigger the check engine light, or even prevent the car from starting. If these issues sound familiar, bring your GL 450 to Mercedes-Benz and have our team of talented certified mechanics guarantee that your aftermarket items were installed perfectly and aren't causing any issue. Getting accessories, particularly aftermarket parts and accessories, or utilizing OEM components first place might cost a little bit more but could help you save substantially from having to get poor work and damage caused by poor installation work corrected.
  • One of the most common and frequent cause is that your 2016 Mercedes-Benz GL 450 gas cap is loose, broken or missing. The gas cap for your 2016 Mercedes-Benz GL 450 serves different purposes. It prevents dangerous 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 defective 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 and be more costly. Luckily, to replace a gas cap isn't costly. If your check engine light turns on instantly after you put gas in your 2016 Mercedes-Benz GL 450, first thing you should check is to make sure the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • The battery is low or dead. The battery in your 2016 Mercedes-Benz GL 450 is each critical. Without a vehicle battery, your vehicle won’t start, light up the road ahead, play the radio or charge your phone. Today’s vehicle 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 current service coupons and specials.
  • New Spark Plugs or Plug Wires are necessary for your 2016 Mercedes-Benz GL 450. The spark plugs are the part of your engine that ignites the air/fuel combination in the combustion chamber of your car. This explosion is what moves the pistons and makes the engine run smooth. 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 old, you will experience a conspicuous 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, leading to more costly repairs.
