Why is my BMW X7 displaying a check engine light?

I recently purchased a BMW X7 and noticed that the check engine light has come on. What could be causing this and how can I fix it?

It's important to address a check engine light as soon as possible. It could indicate a minor issue that can easily be fixed or a more serious problem that could cause damage to your vehicle. It's best to take your car to a certified BMW mechanic to diagnose and fix the issue.

One common reason for a check engine light is a loose or faulty gas cap. Check to make sure the gas cap is securely tightened and if the light persists, bring your car to a mechanic.
