Why is the BMW M3 engine light on?

I recently noticed that the engine light in my BMW M3 is on. What could be causing this? Is it something serious?

The engine light could be on due to various reasons such as a faulty oxygen sensor, a loose gas cap, or even a problem with the catalytic converter. It is important to get this checked by a professional mechanic as soon as possible.

Do you notice any other unusual symptoms such as strange noises or a decrease in performance? If so, it could indicate a more serious issue. It is always best to err on the side of caution and have it checked by a trusted mechanic.

Have you recently replaced the battery in your BMW M3? Sometimes a weak battery can trigger the engine light. Try replacing it and see if the light goes off.
