Check Engine Light Service 2022 Mercedes-Benz CLA 250

What do you do when you’re driving along in your Mercedes-Benz CLA 250 and suddenly, a yellow light illuminates on your dash and says "Check Engine". If you’re like most Mercedes-Benz owners, your heart sinks drastically because you may have absolutely idea about what that light is trying to tell you or how you should react. The fear of the unknown (or the cost of the unknown) can be just as stressful. But take a deep, serene breath and realize the light coming on doesn’t mean you have to pull the car over to the side of the road and call a tow truck, but it is suggested that you get your 2022 Mercedes-Benz CLA 250 checked swiftly. Ignoring that warning could end up causing major, far-reaching damage to costly engine parts.

When your 2022 Mercedes-Benz CLA 250's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can’t correct, a computer turns on your check engine light. This amber or yellow light is typically labeled “check engine” or “service engine soon”, or the light may be nothing more than a picture of an engine, or a picture of the engine with the word “check.”

When the light turns on, the ECM stores an engine code or “trouble code” in its memory that can expeditiously identify the issue, whether it's a sensor or a failing engine part. This code is read with an electronic scan tool that is used by our Mercedes-Benz auto repair mechanics at Plaza Motor Company. There are likewise a number of essentially inexpensive code readers that are designed for do-it-yourselfers, should you prefer that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an experienced professional to determine the definitely correct issue and repair it.

2022 Mercedes-Benz CLA 250 Check Engine Light Codes

The check engine light turning on can be quite intimidating, especially to see that little light on your vehicle’s dashboard suddenly illuminate, but in reality, it is not something that should cause you to shut down in fear right away. If you hear the term, diagnostic trouble codes (DTC), these are just another name for check engine light codes. These are automotive computer codes stored by the ECM, still known as the OBD (on-board computer diagnostic system) in your CLA 250. There are hundreds of different codes that your check engine light can correctly represent. While that sounds daunting, with a little patience, tackling basic diagnostics will give you useful knowledge about your car and will still allow that vital Check Engine Light to do what it is genuinely supposed to do: be your guide.

  • Transmission issues
  • Old Battery
  • Ignition system faults
  • Fuel and air metering systems problems
  • O2 Sensor
  • Computer output circuit issues

If the check engine light in your 2022 Mercedes-Benz CLA 250 starts flashing, that means that the problem needs attention quickly and your Mercedes-Benz should be brought in instantly. This blinking light normally indicates a severe engine misfire allowing unburned fuel to be dumped into the exhaust system. There it can expeditiously raise the temperature of the catalytic converter to a point where damage is likely, requiring an costly and considerable repair.

How many miles can you drive with the check engine light?

Since each check engine code has its own level of severity, it is generally difficult to predict how many miles you can be safe in driving with the warning light on. It could be anything from a bad sensor to plug wires needing to be replaced.

For instance, if the cause of your check engine light coming on was a loose gas cap, if it's tightened, the light will quickly 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 2022 Mercedes-Benz CLA 250 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.

What could cause the check engine light to come on in a 2022 Mercedes-Benz CLA 250?

When your check engine light comes on, this could be as simple as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of an essential 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 ordinarily means something less serious but a flashing check engine light signifies that your vehicle’s engine is in serious trouble and useful service is required expeditiously. If your check engine light is flashing in your 2022 Mercedes-Benz CLA 250, we remarkably advocate 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:

  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2022 Mercedes-Benz CLA 250’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 regularly neglected maintenance, which is why Plaza Motor Company offers a free multi-point examination with every Mercedes-Benz service. If you have an issue with your catalytic converter and don't get it repaired, your 2022 Mercedes-Benz CLA 250 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.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your 2022 Mercedes-Benz CLA 250 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 CLA 250 to Mercedes-Benz and have our team of gifted certified mechanics make sure that your aftermarket items were installed accurately and aren't causing any issue. Getting accessories, exceptionally 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.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Mercedes-Benz CLA 250 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 CLA 250 is having trouble starting, idling rough or has a sudden rapid change in the position of the throttle pedal, this could be a critical sign of a faulty mass airflow sensor.
  • 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 immediately 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 faulty sensor can not only affect your miles per gallon, but it can cause significant damage to your catalytic converter and your 2022 Mercedes-Benz CLA 250's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the specifically correct mix of air and fuel that enters the cylinders in your engine. A faulty O2 sensor can again cause a vehicle to fail an emissions test.
  • One of the most common and frequent cause is that your 2022 Mercedes-Benz CLA 250 gas cap is loose, broken or missing. The gas cap for your 2022 Mercedes-Benz CLA 250 serves multiple purposes. It prevents hazardous 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 faulty 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 expensive. If your check engine light turns on rapidly after you put gas in your 2022 Mercedes-Benz CLA 250, 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.
  • New Spark Plugs or Plug Wires are required for your 2022 Mercedes-Benz CLA 250. The spark plugs are the part of your engine that ignites the air/fuel mix 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 expensive repairs.
  • Your 2022 Mercedes-Benz CLA 250 has a vacuum leak. Every Mercedes-Benz CLA 250 has a vacuum system that performs a wide variety of functions. The vacuum system again 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, exceptionally if they’re exposed to intense heat or extreme cold.
  • The battery is low or dead. The battery in your 2022 Mercedes-Benz CLA 250 is every critical. 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 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.
