Mercedes-Benz Check Engine Light Causes

There are a few reasons the engine symbol among your Mercedes-Benz warning indicators could be triggered. 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 can 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 Aurora drivers can have. If you’re 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 because a faulty oxygen sensor can damage your catalytic converter, which is costly to replace.

Loose-Fitting Gas Cap

If you don’t screw your gas cap in 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 is a bit more involved (though inexpensive) than you might think!

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, you’ll not only set off your engine Mercedes-Benz dashboard light, but you’ll also decrease your fuel economy, 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!
