What Are the Common Mechanical Issues in the Audi A3?

I've heard some people have experienced mechanical issues with their Audi A3. What are some of the most common issues that might arise and how can they be avoided?

One of the common issues with the Audi A3 is the high-pressure fuel pump failure. This can be avoided by using high-quality and clean fuel as well as getting regular maintenance checks on the pump.

Another common issue is the transmission failure. You can prevent this by regularly servicing your transmission fluid and ensuring it's at the correct level.
