If your check engine light is flashing in your 2018 Mercedes-Benz SL 450, we very recommend not to commute the vehicle and schedule Mercedes-Benz service today.

  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2018 Mercedes-Benz SL 450’s exhaust system. The catalytic converter's perform is to turn the carbon monoxide created by the combustion process into carbon dioxide. A damaged catalytic converter is generally 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 2018 Mercedes-Benz SL 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 mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Mercedes-Benz SL 450 is what determines how much fuel is fundamental 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 clear changes, like altitude. If your Mercedes-Benz SL 450 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.
  • Your 2018 Mercedes-Benz SL 450 has a vacuum leak. Every Mercedes-Benz SL 450 has a vacuum system that performs a expanded variety of functions. The vacuum system also helps lower destructive 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 remarkable heat or extreme brisk.
  • The battery is low or dead. The battery in your 2018 Mercedes-Benz SL 450 is every necessary. 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 certainly 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.
  • One of the most common and bountiful cause is that your 2018 Mercedes-Benz SL 450 gas cap is loose, damaged or missing. The gas cap for your 2018 Mercedes-Benz SL 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 classical 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 instantly after you put gas in your 2018 Mercedes-Benz SL 450, 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 replaced. The Oxygen sensor, common 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 persuasive 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 2018 Mercedes-Benz SL 450's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to hint the right 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.
  • New Spark Plugs or Plug Wires are fundamental for your 2018 Mercedes-Benz SL 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 classical, 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 expensive repairs.
  • Issues with each aftermarket items. An aftermarket alarm, exhaust or distinct item can wreak havoc on your 2018 Mercedes-Benz SL 450 if it’s not installed properly.
