The vacuum system also helps cut 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, particularly if they’re exposed to dominant heat or extreme freezing.
  • The battery is scanty or dead. The battery in your 2015 Mercedes-Benz SL 400 is every laborious. 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.

  • Your mass airflow sensor (known as MAF) needs to be changed. The mass airflow sensor in your Mercedes-Benz SL 400 is what determines how much fuel is imperative 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 genuine changes, like altitude. If your Mercedes-Benz SL 400 is having trouble starting, idling rough or has a sudden change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
  • Your O2 Sensor (Oxygen Sensor) needs to be changed. 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 car will be less cooperative 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 2015 Mercedes-Benz SL 400's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to pick the prudent variety 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.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or added item can wreak havoc on your 2015 Mercedes-Benz SL 400 if it’s not installed appropriately. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prevent the car from starting.

Getting accessories, particularly aftermarket parts and accessories, or using OEM parts first place might rate a little bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
  • New Spark Plugs or Plug Wires are imperative for your 2015 Mercedes-Benz SL 400. The spark plugs are the part of your engine that ignites the air/fuel variety in the combustion chamber of your car. 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 old, you will experience poor performance and reduced power. In a bit 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.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2015 Mercedes-Benz SL 400’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 fixed, your 2015 Mercedes-Benz SL 400 will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy.
