What should I do if my BMW M3's check engine light turns on?

I recently noticed that the check engine light in my BMW M3 has turned on. I'm wondering what could be causing this and what I should do to fix it.

First, don't panic. The check engine light can indicate a variety of issues, both minor and major. The best course of action is to schedule a diagnostic test at a certified BMW dealership or mechanic. They will be able to pinpoint the exact issue and provide you with the best solution. Don't wait too long to get it checked out, as a small issue can turn into a larger, more expensive problem.

One common reason for a check engine light in a BMW M3 is a loose gas cap. Make sure to check if your gas cap is securely tightened. If the light persists, then it may be a more serious issue and you should seek professional help.

Another possible cause for the check engine light is a faulty oxygen sensor. This can negatively impact the fuel economy and emissions of your M3. It's important to get this fixed as soon as possible to avoid further damage to your car.
