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

When your check engine light comes on, this could be as simple 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 colossal repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow mostly means something fewer strict but a flashing check engine light indicates that your vehicle’s engine is in strict trouble and service is crucial rapidly. If your check engine light is flashing in your Mercedes-Benz GLS 450, we extremely recommend not to drive the vehicle and schedule Mercedes-Benz service now. Below is a list of the most daily 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 car will be less proper 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 Mercedes-Benz GLS 450's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to select the decent range 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.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak havoc on your Mercedes-Benz GLS 450 if it’s not installed accurately. These aftermarket parts and accessories can discharge the battery, trigger the check engine light, or even prevent the car from starting. If these issues sound prevalent, bring your GLS 450 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 little bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
  • New Spark Plugs or Plug Wires are needed for your 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 car. This explosion is what moves the pistons and makes the engine run. The spark plug wires bring 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 little 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, main to more expensive repairs.
  • 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 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 pronounced changes, like altitude. If your Mercedes-Benz GLS 450 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.
  • Your Mercedes-Benz GLS 450 has a vacuum leak. Each Mercedes-Benz GLS 450 has a vacuum system that performs a wide assortment 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 dry out and crack, especially if they’re exposed to grand heat or extreme congenial.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your Mercedes-Benz GLS 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 Mercedes-Benz of Chesterfield 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 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 other problems from overheating.
  • One of the most prevalent and bountiful cause is that your Mercedes-Benz GLS 450 gas cap is loose, damaged or missing. The gas cap for your 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 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 abruptly after you put gas in your Mercedes-Benz GLS 450, first thing you should check is to make convinced 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 Mercedes-Benz GLS 450 is each grand. 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 little decades ago, and they don't genuinely require maintenance. The rate of a new one depends on the type of Mercedes-Benz you drive, but check our current service coupons and specials.
