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

When your check engine light comes on, this could be as prevailing as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a exacting problem that could cause exacting 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 steady glow consistently means something less exacting but a flashing check engine light indicates that your vehicle’s engine is in exacting trouble and service is paramount hastily. If your check engine light is flashing in your Mercedes-Benz, we extraordinarily advocate not to commute the car and schedule Mercedes-Benz service today. Below is a list of the most legal reasons your check engine light can come on:

  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak havoc on your Mercedes-Benz if it’s not installed properly. These aftermarket parts and accessories can discharge the battery, trigger the check engine light, or even stop the vehicle from starting. If these issues sound prevalent, bring your 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, particularly aftermarket parts and accessories, or using OEM parts first place might estimate a tiny bit more but could save you money from having to get poor work and wear and tear caused by poor installation work corrected.
  • The battery is low or dead. The battery in your Mercedes-Benz is every essential. 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 few decades ago, and they don't really require maintenance. The estimate of a new one depends on the type of Mercedes-Benz you drive, but check our actual service coupons and specials.
  • Your mass airflow sensor (known as MAF) needs to be replenished. The mass airflow sensor in your Mercedes-Benz is what determines how much fuel is essential 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 accomplished changes, like altitude. If your Mercedes-Benz is having trouble starting, idling rough or has a rapid change in the position of the throttle pedal, this could be a sign of a detrimental mass airflow sensor.
  • New Spark Plugs or Plug Wires are essential for your Mercedes-Benz. 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 detrimental 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 wear and tear to ignition coils and O2 sensors, major to more expensive repairs.
  • One of the most accepted and countless cause is that your Mercedes-Benz gas cap is loose, damaged or missing. The gas cap for your Mercedes-Benz 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 detrimental 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 expensive. If your check engine light turns on immediately after you put gas in your Mercedes-Benz, 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.
  • Your O2 Sensor (Oxygen Sensor) needs to be replenished. 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 vehicle will be less potential 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 's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to indicate the right mixture of air and fuel that enters the cylinders in your engine. A detrimental O2 sensor can also cause a car to fail an emissions test.
  • Your Mercedes-Benz has a vacuum leak. Every Mercedes-Benz has a vacuum system that performs a wide mixture of functions. The vacuum system also helps lower damaging 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 important heat or extreme frigid.
  • Your catalytic converter is detrimental or going detrimental. The catalytic converter is a part of your Mercedes-Benz ’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 every Mercedes-Benz service. If you have an issue with your catalytic converter and don't get it repaired, your Mercedes-Benz 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.
