Why is my Volkswagen Polo's check engine light on?

I've noticed that the check engine light on my Volkswagen Polo has been on for a few days now. What could be causing this and should I be worried?

The check engine light could be indicating a more serious problem, such as a faulty oxygen sensor or catalytic converter. It's important to get it diagnosed and repaired as soon as possible to avoid further damage to your car.

Have you recently gotten an oil change or had any other service done on your car? If so, it's possible that a sensor was not reset properly, causing the check engine light to come on. Double check with the mechanic who serviced your car.

It's possible that your check engine light is on due to a minor issue like a loose gas cap. However, it's always best to get it checked out by a mechanic just to be safe. Schedule an appointment at your local Volkswagen dealership to have it inspected.
