If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less effective 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 CLS 550's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to choose the right range of air and fuel that enters the cylinders in your engine. A bad O2 sensor can also cause a vehicle to fail an emissions test.

The mass airflow sensor in your Mercedes-Benz CLS 550 is what determines how much fuel is fundamental to run your engine efficiently by measuring the reward of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to certain changes, like altitude.

Without a vehicle battery, your vehicle won’t start, light up the road ahead, play the radio or charge your phone. Today’s vehicle batteries last much longer than they did several decades ago, and they don't truly require maintenance. The rate of a new one depends on the type of Mercedes-Benz you drive, but check our regular service coupons and specials.
• One of the most commonplace and frequent cause is that your 2018 Mercedes-Benz CLS 550 gas cap is loose, damaged or missing. The gas cap for your 2018 Mercedes-Benz CLS 550 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 departed 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.

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.
• Your 2018 Mercedes-Benz CLS 550 has a vacuum leak. Every Mercedes-Benz CLS 550 has a vacuum system that performs a wide range of functions. The vacuum system also helps lower bad 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 important heat or extreme freezing.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2018 Mercedes-Benz CLS 550’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 ordinarily 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 2018 Mercedes-Benz CLS 550 will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy.
