What to do when my Volkswagen Polo's check engine light turns on?

I have a Volkswagen Polo and recently the check engine light turned on. It is driving me crazy and I am not sure what to do about it. Can anyone help me figure out how to fix it?

Don't panic, the check engine light could indicate a minor issue or a faulty sensor. The best thing to do is to get your car checked by a mechanic to determine the exact cause. In the meantime, make sure your gas cap is securely tightened as a loose cap can also trigger the light.

First, check your car's manual to see if there are any recommended actions to take when the check engine light turns on. If not, it is best to bring your car to a trusted mechanic who can diagnose and fix the problem. Ignoring the light can result in further damage to your car.

The most common reason for the check engine light turning on is a faulty oxygen sensor. This can affect your car's fuel economy and emissions, so it's best to get it checked and replaced if needed. Don't wait too long, as a faulty oxygen sensor can also lead to other engine problems.
