How do I troubleshoot a check engine light on my BMW 2 Series?

I recently noticed that the check engine light on my BMW 2 Series has turned on. What could be causing this and what steps should I take to troubleshoot the issue?

First, check your gas cap to make sure it is properly closed and sealed. If that's not the issue, take your car to a trusted mechanic or dealership to have the error code read. This will give you a better idea of what is causing the check engine light to turn on. Avoid driving the car for prolonged periods of time until the issue is resolved.

Make sure to also check your vehicle's fluids and schedule a regular maintenance check if it's been a while. Low oil, coolant, or transmission fluid levels can also trigger the check engine light, so it's important to keep these topped off.
