Has the BMW check engine light appeared on your dashboard? This may indicate that your BMW needs to be serviced, but it also may mean that you simply need to complete a BMW check engine light reset. Find out what you need to do when you see the BMW check engine light symbol from the experts at the BMW of Gwinnett Place service center.

BMW Check Engine Light Symbol: Common Causes

There are a multitude of reasons that the BMW check engine light symbol will appear, some of which are certainly more serious than others. A few common causes include:

  • Loose gas cap: First and foremost, check that your gas cap is securely tightened. If this is the case, a BMW check engine light reset may be as simple as properly sealing your gas cap.
  • Failing oxygen sensor: The oxygen sensor monitors the amount of unburned oxygen in the exhaust system and is a crucial component of the emissions system. When it fails, the BMW check engine light may ignite on your dashboard screen, and you will likely also notice decreased fuel economy returns.
  • Failing mass air flow sensor: This system measures how much air enters the engine, and complications with the mass air flow sensor may trigger the BMW check engine light. Schedule service with BMW of Gwinnett Place near Marietta to determine if this is the reason behind your BMW check engine light.
  • Damaged spark plugs or wires: If you suspect spark plug or wire damage, bring your BMW to our dealership as soon as possible. Spark plugs are essential to your vehicle starting, so without them, your vehicle will be undriveable. 
  • Failing catalytic converter: The catalytic converter converts gases into less harmful ones, like carbon dioxide. Issues with the catalytic converter typically arise when other problems have been ignored.

Remember, there very well may be other issues at play that prompt the BMW check engine light symbol to illuminate. These only represent a handful of common causes.
