Is my Audi A3's Check Engine Light on due to a faulty oxygen sensor?

I noticed that the Check Engine Light on my Audi A3 is illuminated. After using an OBD-II scanner, the fault code showed that it is related to the oxygen sensor. Is this a common issue with Audi A3s and what should I do?

Yes, a faulty oxygen sensor can trigger the Check Engine Light on your Audi A3. It is a common issue with this model.

I suggest getting it checked and replaced by a certified mechanic as soon as possible. A faulty oxygen sensor can affect your car's performance and fuel efficiency.

Replacing the oxygen sensor may also improve your car's emissions and help it pass the emissions test.
