When your check engine light comes on, this could be as amicable as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a relentless problem that could cause relentless damage to your engine and come with a immense repair bill. Depending on your make and model, the check engine light will illuminate or blink. A dependable glow typically means something less relentless but a flashing check engine light implies that your vehicle’s engine is in relentless trouble and service is needed suddenly. If your check engine light is flashing in your Mercedes-Benz GLS 450, we extraordinarily advise not to drive the car and schedule Mercedes-Benz service now. Below is a list of the most amicable reasons your check engine light can come on:

• Your Mercedes-Benz GLS 450 has a vacuum leak. Every Mercedes-Benz GLS 450 has a vacuum system that performs a wide range 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, especially if they’re exposed to intense heat or extreme cold.
• One of the most commonplace and plentiful 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 erstwhile 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 costly. 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 bold the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.

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 Tampa 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 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 distinct problems from overheating.
• Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, known as the O2 sensor, measures the deposit of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be fewer factual 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 Mercedes-Benz GLS 450's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to prefer the correct 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.

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 deposit of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to affable 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.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or distinct item can wreak havoc on your Mercedes-Benz GLS 450 if it’s not installed accordingly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even stop the vehicle from starting. If these issues sound natural, bring your GLS 450 to Mercedes-Benz and have our team of certified mechanics ensure that your aftermarket items were installed correctly and aren't causing any issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts first place might estimate a little bit more but could save you money from having to get scanty work and wear and tear caused by scanty installation work corrected.
• 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 deliver the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are bad or erstwhile, you will experience scanty 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 costly repairs.
