How to Reset the BMW Check Engine Light

If you notice the BMW check engine light on your dashboard, don’t panic. This could indicate that you need to schedule a service appointment with our service team at United BMW. It could also mean you simply need to complete a BMW check engine light reset. Either way, trust our team near Roswell to help you get your BMW safely back on local roads.

BMW Check Engine Light Symbol: Common Causes

When you notice the BMW check engine light symbol appearing, there could be a number of reasons why. These can be serious. A few common reasons 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 United BMW near Roswell 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 inoperable.
• 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.

Also remember that there could be other issues at play that could cause the BMW check engine light symbol to appear. Make sure you contact our service experts to try and solve the issue before you reset your light.

BMW Check Engine Light Reset

When the BMW check engine light appears, we recommend that you bring your vehicle in for service. However, if you’ve already solved the issues and the light is still on, you’ll want to perform a BMW check engine light reset. Here’s how you can do this:

• Disconnect the negative battery cable for 30 to 60 seconds, and then reconnect it and start your car.
• Check your gas cap, as previously mentioned.
• Have the service technicians at United BMW take a look again to ensure everything is functioning properly.
