The check engine light can be triggered by a variety of issues, such as a loose gas cap, faulty sensors, or a more serious problem with the engine. It's important to have a diagnostic check done to determine the exact cause.

R

In my experience, the check engine light in Audi A3s often turns on due to a faulty oxygen sensor. This is a relatively easy fix, but if left untreated it can lead to decreased fuel efficiency and potential damage to the catalytic converter.

I've had the same issue with my Audi A3 and it turned out to be a faulty ignition coil. It's best to get this fixed right away to avoid any further damage to the engine.
