The engine malfunction light can come on for a variety of reasons, such as a faulty sensor, a misfiring engine, or a faulty catalytic converter. It's important to get your car checked by a mechanic to determine the exact cause of the light turning on.

One possible reason for the engine malfunction light coming on could be a loose or faulty gas cap. Make sure the gas cap is properly tightened and see if the light turns off. If it doesn't, it's best to take your car to a mechanic for a proper diagnosis.

If you recently filled up your gas tank, it's possible that you accidentally used the wrong type of gasoline. This can cause the engine malfunction light to come on. Make sure you are using the recommended gasoline for your BMW 3 Series to prevent this issue.
