Have you ever noticed a yellow/orange light that seems to scream “check engine” on your Mercedes’ dashboard? Having to see this light every time can be frustrating and worse if you cannot tell what the issue is.
The “check engine light” in your car helps to warn you of impending engine problems and ignoring it could lead to engine damage. In this guide, we will explain the common reasons why the “check engine” light comes on, and how to avoid them.
Why Does the “Check Engine” Light Come on in a Car
To ensure that your car’s check engine light stops showing at odd times, you need to understand why the light comes on in the first place. This light in your car’s dashboard is a feature that allows you to take proper care of your engine.
It alerts you immediately there is the slightest chance of a problem in your car’s engine system so you can take measures to fix it before the situation escalates and puts your engine at risk. So, one of the reasons why this light could come up is if one of the engine’s components has failed or is damaged.
Some of the key components you should consider in this case are oxygen sensors, gas caps, fuel injectors, spark plugs, ignition coils, and many others.
How to ensure that the Check Engine Light in Your Mercedes Does Not Come on
If you want to prevent the “check engine” light from coming on in your Mercedes, then you have to keep your car in the best condition so nothing goes wrong to trigger the Engine Control unit (ECU) to turn the light on.
Here, we have highlighted a few things you can do on a regular basis so your engine works smoothly and the “check engine” light is not a pain that you have to deal with anytime soon.
1. Regular Engine Maintenance
One of the best ways to keep your Mercedes at its best is to have a routine for maintenance and to stick with it. Doing this helps to avoid problems with the engine and thus, keeps the engine warning light off.
The maintenance for your engine involves simple steps such as regular oil checks and changes; inspect your engine oil and change it once it is due for an oil change. You should also ensure you use the right type of oil and replace other engine parts like the spark plug and ignition coil when it is time.
2. Fuel System Maintenance
The engine is not the only part that needs to be looked after. If anything goes wrong with the fuel system, the engine will be affected and the check engine light will come on to warn you. Hence, conduct regular inspections and timely repairs of any damaged part.
You should also make sure that you use high-quality fuel so the engine runs smoothly without issues.
3. Ensure Battery Health
Some engine parts and functions rely on a working battery, so if the battery in your car ever gets faulty, the engine function could be compromised and this will trigger the check engine light to come on. Hence, ensure that you clean the battery often and prevent dirt accumulation or corrosion around the battery terminals.
4. Protect the Engine in Extreme Weather
You may notice that the “check engine” light comes on more often when the weather condition is not favorable. The engine needs optimal temperature to run efficiently. However, if there is excess heat or extreme cold, then the engine function could be impaired.
To prevent this, you need to put measures in place to protect your car’s engine. You should park under a shaded area so your car’s engine is not exposed to direct sunlight and use engine covers when the weather is too cold.
