If your check engine light is flashing in your Mercedes-Benz GLS 450, we exceptionally recommend not to commute the vehicle and schedule Mercedes-Benz service today. Below is a list of the most sufficient reasons your check engine light can come on:

  • Your mass airflow sensor (known as MAF) needs to be replenished. The mass airflow sensor in your Mercedes-Benz GLS 450 is what determines how much fuel is crucial to run your engine efficiently by measuring the fee of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to definite 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 O2 Sensor (Oxygen Sensor) needs to be replenished. The Oxygen sensor, known as the O2 sensor, measures the fee of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less apt 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 represent the prudent mixture 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 divergent item can wreak havoc on your Mercedes-Benz GLS 450 if it’s not installed properly. These aftermarket parts and accessories can deposit the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound prevailing, transport your GLS 450 to Mercedes-Benz and have our team of certified mechanics ensure that your aftermarket items were installed properly 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.
  • 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 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 fixed, 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 divergent problems from overheating.
  • Your 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 detrimental 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 intense heat or extreme cold.
  • One of the most routine and many 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 departed 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 promptly after you put gas in your Mercedes-Benz GLS 450, first thing you should check is to make satisfied the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • The battery is poor or dead. The battery in your Mercedes-Benz GLS 450 is every vital. 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 lot decades ago, and they don't surely require maintenance. The price of a new one depends on the type of Mercedes-Benz you drive, but check our familiar service coupons and specials.
  • New Spark Plugs or Plug Wires are crucial for your Mercedes-Benz GLS 450. The spark plugs are the part of your engine that ignites the air/fuel mixture 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 bad or departed, 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, major to more expensive repairs.
