The Top 5 Reasons Your Check Engine Light Is On

Mercedes A-Class

One of the most unwelcoming sights to see when you are driving your vehicle is your check engine light turning on. It becomes another thing to add to your large to-do list and almost always at a time when you least expect it. Thankfully, Mercedes-Benz Brampton of Brampton is here to take care of your vehicle. Our trained technicians have access to all of the best Mercedes-Benz parts to get your vehicle fixed quickly and efficiently. We can also give you tips and tricks on how to prevent these situations in the future. Here are the top five reasons why your check engine light has turned on in your vehicle….

Loose-Fitting Gas Cap

Filling up your vehicle with gas is so common that you could probably do it in your sleep. Since we are so comfortable doing this, we tend to miss the simple things about the process—like putting the gas cap back on correctly. When the gas cap is not secure, vapors from the fuel tank leak out and make your engine light turn on. Make sure you are always securing the gas cap! If the light doesn’t turn off after you have fixed that, then our service department can reset your vehicle’s computer codes.

Oxygen Sensor

A faulty oxygen sensor is another cause for your gas light to turn on. If this is diagnosed, it should be replaced immediately. The oxygen sensor can damage your vehicle’s catalytic converter if you do not take care of it. Avoiding this costly repair is crucial for your wallet, so make sure that you bring it in today, even just for a simple checkup we are always ready to help.

Spark Plugs

An important rule of thumb is to replace your spark plugs every 25,000 miles to avoid eventual failure. Failing to replace your spark plugs at the appropriate time will result in your engine light turning on. Our service team can run a quick diagnostics test to check if spark plugs are the issue. If so, we can replace them.

Mass Airflow Sensor

If you fail to replace your vehicle’s air filter, the check engine light can turn on. A faulty air filter will result in lower gas mileage, more emissions, and stalling in some cases. During a regular maintenance check, we can look at your mass airflow sensor and service your vehicle if needed.

Catalytic Converter

The failure of the catalytic converter is the worst case scenario as a result of your check engine light turning on. Our service team can diagnose this issue by running a vehicle check and finding a specific code. If it does need replacement, your best bet is getting that done by the professionals at Mercedes-Benz Brampton.

So if you see your check engine light on, please don’t ignore it. Make an appointment with your Mercedes-Benz dealer in Brampton so we can immediately diagnose and fix your problem. Our extremely experienced and expert service staff will make a quick fix and provide you with tips on avoiding issues down the road.

We look forward to your Service with us!
