Depending on your make and model, the check engine light will illuminate or blink.

If your check engine light is flashing in your Mercedes-Benz, we very recommend not to drive the vehicle and schedule Mercedes-Benz service today. Below is a list of the most common reasons your check engine light can come on:

• Your Mercedes-Benz has a vacuum leak. Each Mercedes-Benz has a vacuum system that performs a wide variety of functions. The vacuum system likewise helps lower unhealthy 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 intense heat or extreme cold.
• Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Mercedes-Benz is what determines how much fuel is required 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 is having trouble starting, idling rough or has a sudden rapid change in the position of the throttle pedal, this could be a vital sign of a damaged mass airflow sensor.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your Mercedes-Benz 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.

Getting accessories, particularly aftermarket parts and accessories, or using 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.
• One of the most common and frequent cause is that your Mercedes-Benz gas cap is loose, broken or missing. The gas cap for your Mercedes-Benz serves different 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 damaged 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 pricey. Luckily, to replace a gas cap isn't costly. If your check engine light turns on instantly after you put gas in your Mercedes-Benz, 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.
• The battery is low or dead. The battery in your Mercedes-Benz is each vital. 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 genuinely 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 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 swiftly 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 damaged sensor can not only affect your miles per gallon, but it can cause serious damage to your catalytic converter and your Mercedes-Benz 's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the precisely correct combination of air and fuel that enters the cylinders in your engine. A damaged O2 sensor can likewise cause a car to fail an emissions test.
• New Spark Plugs or Plug Wires are required for your Mercedes-Benz. 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 noticeable 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, leading to more costly repairs.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your Mercedes-Benz ’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 normally caused by consistently neglected maintenance, which is why Coggin Automotive Group offers a free multi-point check with each Mercedes-Benz service. If you have an issue with your catalytic converter and don't get it repaired, your Mercedes-Benz 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 other dangerous problems from overheating.
