The most common reason for a check engine light in BMWs is a faulty oxygen sensor. You can try using an OBD II scanner to read the trouble codes and determine the specific issue. It could also be a loose gas cap or a minor emissions issue. If the issue persists, it's best to take it to a mechanic for further diagnosis.

I had the same issue with my BMW and it turned out to be a faulty mass air flow sensor. It's best to take it to a professional mechanic to properly diagnose the issue and prevent any further damage to your car.

Check your BMW's manual for any specific instructions on how to reset the check engine light. It could be a simple fix that you can do yourself without spending any money on a mechanic.
