What could cause the check engine light to come on in a 2012 Mercedes-Benz C250?

When your check engine light comes on, this could be as comfortable as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a adequate problem that could cause adequate damage to your engine and come with a abundant repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow generally means something less adequate but a flashing check engine light indicates that your vehicle’s engine is in adequate trouble and service is fundamental urgently. If your check engine light is flashing in your 2012 Mercedes-Benz C250, we highly recommend not to drive the vehicle and schedule Mercedes-Benz service at this moment. Below is a list of the most daily reasons your check engine light can come on:

  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Mercedes-Benz C250 is what determines how much fuel is imperative to run your engine efficiently by measuring the drain of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to clear changes, like altitude. If your Mercedes-Benz C250 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 detrimental mass airflow sensor.
  • New Spark Plugs or Plug Wires are imperative for your 2012 Mercedes-Benz C250. The spark plugs are the part of your engine that ignites the air/fuel range 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 erstwhile, 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.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or alternative item can wreak havoc on your 2012 Mercedes-Benz C250 if it’s not installed well. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even impede the vehicle from starting. If these issues sound typical, bring your C250 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, chiefly 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 wear and tear caused by poor installation work corrected.
  • One of the most simple and innumerable cause is that your 2012 Mercedes-Benz C250 gas cap is loose, damaged or missing. The gas cap for your 2012 Mercedes-Benz C250 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 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 expensive. If your check engine light turns on expeditiously after you put gas in your 2012 Mercedes-Benz C250, first thing you should check is to make confident the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Your 2012 Mercedes-Benz C250 has a vacuum leak. Every Mercedes-Benz C250 has a vacuum system that performs a wide variety of functions. The vacuum system also helps lower down 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, chiefly if they’re exposed to exciting heat or extreme cold.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, typical as the O2 sensor, measures the drain of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be fewer productive 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 2012 Mercedes-Benz C250's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to choose the honest range 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.
  • The battery is poor or dead. The battery in your 2012 Mercedes-Benz C250 is every decisive. 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 assorted decades ago, and they don't really require maintenance. The price of a new one depends on the type of Mercedes-Benz you drive, but check our typical service coupons and specials.
  • Your catalytic converter is detrimental or going detrimental. The catalytic converter is a part of your 2012 Mercedes-Benz C250’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 frequently 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 revamped, your 2012 Mercedes-Benz C250 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 alternative problems from overheating.
