Ignoring that warning could end up causing major damage to expensive engine components.

This amber or yellow light is typically labeled “check engine” or “service engine soon”, or the light may be nothing more than a picture of an engine, or a picture of the engine with the word “check.”

When the light turns on, the ECM stores an engine code or “trouble code” in its memory that identifies as the issue, whether it's a sensor or a failing engine part. This code is read with an electronic scan tool that is used by our Mercedes-Benz auto repair mechanics at Plaza Motor Company. There are also a number of relatively inexpensive code readers that are designed for do-it-yourselfers, should you select that route too.

What could cause the check engine light to come on in a 2021 Mercedes-Benz E350?

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 contentious problem that could cause contentious damage to your engine and come with a large repair bill. Depending on your make and model, the check engine light will illuminate or blink. A consistent glow typically means something fewer contentious but a flashing check engine light implies that your vehicle’s engine is in contentious trouble and service is needed shortly. If your check engine light is flashing in your 2021 Mercedes-Benz E350, we highly endorse not to drive the vehicle and schedule Mercedes-Benz service today.

If your spark plugs or spark plug wires are bad 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 damage to ignition coils and O2 sensors, extensive to more lavish repairs.

As a part of the engine management system, the mass airflow sensor helps adjust to affectionate changes, like altitude. If your Mercedes-Benz E350 is having trouble starting, idling rough or has a hasty change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
• The battery is low or dead. The battery in your 2021 Mercedes-Benz E350 is every imposing. 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 really require maintenance. The price of a new one depends on the type of Mercedes-Benz you travel to work, but check our present service coupons and specials.
• Your 2021 Mercedes-Benz E350 has a vacuum leak. Every Mercedes-Benz E350 has a vacuum system that performs a wide variety of functions. The vacuum system also helps lower serious 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 extraordinary heat or extreme bitter.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2021 Mercedes-Benz E350’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 2021 Mercedes-Benz E350 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 added problems from overheating.
• Your O2 Sensor (Oxygen Sensor) needs to be replaced. 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 competent 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 2021 Mercedes-Benz E350's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to prefer the right range of air and fuel that enters the cylinders in your engine. A bad O2 sensor can also cause a vehicle to fail an emissions test.
• One of the most acceptable and frequent cause is that your 2021 Mercedes-Benz E350 gas cap is loose, damaged or missing. The gas cap for your 2021 Mercedes-Benz E350 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 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 lavish. If your check engine light turns on immediately after you put gas in your 2021 Mercedes-Benz E350, 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.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or added item can wreak havoc on your 2021 Mercedes-Benz E350 if it’s not installed appropriately. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even avert the vehicle from starting. If these issues sound affectionate, bring your E350 to Mercedes-Benz and have our company 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 cost a little bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
