Mercedes-Benz Check Engine Light Causes

If your Mercedes-Benz engine light is on, you may be nervous. There are a few reasons why the check engine light in your Mercedes-Benz could be triggered. If your dashboard light is on, take a moment to review the most common culprits below, and if you need help with navigating any issues raised by your Mercedes-Benz dashboard lights, don’t hesitate to contact our service garage!

Oxygen Sensor Warning

A faulty oxygen sensor may cause your Mercedes-Benz check engine light to turn on. Among the long list of Mercedes-Benz check engine light codes, this is one of the more innocuous problems Toronto drivers can have.

For those wondering, “Can I drive my Mercedes-Benz with the check engine light on?”, you certainly can if this is your problem. That said, you should bring your vehicle in immediately, as a faulty oxygen sensor can damage your catalytic converter, which will be costly to replace.

Loose-Fitting Gas Cap

If you don’t screw your gas cap after filling up tightly enough, it can set off your Mercedes-Benz check engine light. Obviously, this problem is easy to fix. The one thing to bear in mind, however, is that you may need to reset your Mercedes-Benz engine light. In this case, we recommend you swing by our garage on your lunch break, as the process of resetting the check engine light for your Mercedes-Benz model is a bit more involved (though inexpensive) than you might think! In this case, how to reset your check engine light wouldn’t be too difficult.

Catalytic Converter

Your catalytic converter helps to regulate your emissions. Some of the materials that it’s made of include precious metals that are quite valuable. That means that it can be costly to replace, but it’s necessary. You won’t be able to pass your emissions test without one. Unfortunately, catalytic converters are often stolen due to their high value, so if your Mercedes-Benz warning indicator for the engine goes off, let us double-check to make sure that your catalytic converter is in good shape!

Mass Airflow Sensor

If you haven’t changed your engine’s air filter in some time, you’ll not only set off your Mercedes-Benz dashboard light, but you’ll also decrease your fuel economy, affect your acceleration, and increase your emissions. This is a simple fix and incredibly affordable.

Old Spark Plugs

You need to replace your spark plugs every 40,000 km. These plugs create the spark that ignites the fuel in your combustion chamber. If you’ve forgotten to change them out, it can trigger your Mercedes-Benz check engine light, all while decreasing fuel economy, slowing acceleration, creating misfires, and more!
