Why is my BMW 4 Series dashboard displaying a check engine light?

I recently noticed that the check engine light in my BMW 4 Series turned on. What could be causing this issue and how can I fix it? Any advice is greatly appreciated!

There are a few possible reasons why the check engine light is on in your BMW 4 Series. It could be a simple issue like a loose gas cap, or it could be a more serious problem with your engine. The best course of action is to bring your car to a certified BMW mechanic for a diagnostic test.

In my experience, a common cause for the check engine light to turn on in a BMW 4 Series is a faulty oxygen sensor. This is a relatively simple and inexpensive fix, but it is important to get it taken care of to prevent further damage to your car.
