Why is the engine light on in my Audi A2?

I recently noticed that the engine light on my Audi A2 has turned on. I'm unsure why this is happening and what steps I should take to resolve it. Any insight would be greatly appreciated.

The engine light could be on for a variety of reasons, but one common cause is a faulty oxygen sensor. I recommend taking your car to a mechanic and having them run a diagnostic test to determine the exact issue.

The engine light could also indicate a problem with your car's catalytic converter. This is usually a more expensive fix, so I suggest getting a second opinion from a trusted mechanic before making any repairs.
