What could cause the check engine light to come on in a 2015 Mercedes-Benz C 350?

When your check engine light comes on, this could be as simple as tightening or replacing your gas cap. Again, the check engine light could also be a warning of a meaningful problem that could cause serious damage to your engine and come with a hefty and pricey repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady and continuous glow typically means something less serious but a flashing check engine light reveals that your vehicle’s engine is in serious trouble and useful service is required rapidly. If your check engine light is flashing in your 2015 Mercedes-Benz C 350, we immensely suggest not to drive the car and schedule Mercedes-Benz service today. Below is a list of the most common reasons your check engine light can come on:

  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your 2015 Mercedes-Benz C 350 if it’s not installed perfectly. These aftermarket components and accessories can drain the battery, trigger the check engine light, or even prevent the car from starting. If these issues sound familiar, bring your C 350 to Mercedes-Benz and have our team of talented certified mechanics ensure that your aftermarket items were installed accurately and aren't causing any issue. Getting accessories, exceptionally aftermarket parts and accessories, or utilizing OEM components first place might cost a little bit more but could help you save substantially 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 2015 Mercedes-Benz C 350’s exhaust system. The catalytic converter's function is to turn the carbon monoxide created by the combustion process into carbon dioxide. A broken catalytic converter is usually caused by constantly neglected maintenance, which is why Plaza Motor Company offers a complimentary multi-point examination with every Mercedes-Benz service. If you have an issue with your catalytic converter and don't get it repaired, your 2015 Mercedes-Benz C 350 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 other delicate problems from overheating.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. 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 more quickly and your car will be less efficient when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A broken sensor can not only affect your miles per gallon, but it can cause serious damage to your catalytic converter and your 2015 Mercedes-Benz C 350's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the exactly correct combination of air and fuel that enters the cylinders in your engine. A broken O2 sensor can again cause a vehicle to fail an emissions test.
  • The battery is low or dead. The battery in your 2015 Mercedes-Benz C 350 is every essential. Without a vehicle battery, your vehicle won’t start, light up the road in front, 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 drive, but check our current service coupons and specials.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Mercedes-Benz C 350 is what determines how much fuel is necessary 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 certain changes, like altitude. If your Mercedes-Benz C 350 is having trouble starting, idling rough or has a sudden speedy change in the position of the throttle pedal, this could be a crucial sign of a broken mass airflow sensor.
  • Your 2015 Mercedes-Benz C 350 has a vacuum leak. Every Mercedes-Benz C 350 has a vacuum system that performs a wide variety of functions. The vacuum system again 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, exceptionally if they’re exposed to intense heat or extreme cold.
  • New Spark Plugs or Plug Wires are necessary for your 2015 Mercedes-Benz C 350. The spark plugs are the part of your engine that ignites the air/fuel combination in the combustion chamber of your car. This explosion is what moves the pistons and makes the engine run smooth. 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 old, you will experience a conspicuous poor performance and decreased 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, leading to more pricey repairs.
  • One of the most common and frequent cause is that your 2015 Mercedes-Benz C 350 gas cap is loose, broken or missing. The gas cap for your 2015 Mercedes-Benz C 350 serves multiple purposes. It prevents dangerous 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 broken 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 and be more expensive. Luckily, to replace a gas cap isn't pricey. If your check engine light turns on promptly after you put gas in your 2015 Mercedes-Benz C 350, 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.

Will the check engine light reset itself?

The check engine light on your 2015 Mercedes-Benz C 350 will usually shut itself off if the issue or code that caused it to turn on is fixed. For instance, if the cause of your check engine light coming on was a loose gas cap, if it's tightened, the light will instantly turn itself off. Still, if your catalytic converter is working accurately, and you did a lot of stop-and-go driving, that may have turned on the check engine light due to the high usage of the converter. In most cases, your 2015 Mercedes-Benz C 350 light will go off after about 20-40 miles. If you drive over that amount and the light is still on, you will need to bring it in to Plaza Motor Company so the light and code can be double-checked and reset.
