Common Issues with the Audi A3 Engine

I've been having some issues with my Audi A3's engine lately. Can you give me some advice on the most common problems and how to address them?

One of the most common issues with the Audi A3 engine is the oxygen sensor failing. This can cause issues with the car's fuel economy and emissions. The best solution is to get the sensor replaced by a reputable mechanic.

Another common issue is the ignition coil failing, which can result in misfiring and a decrease in engine power. It's important to get this fixed as soon as possible, as it can lead to further damage if ignored.

If your Audi A3 is experiencing rough idling or stalling, it could be due to a clogged fuel filter. It's recommended to get the filter replaced every 30,000 miles to prevent these issues.
