What are some common issues with Audi cars and how can they be prevented?

I recently purchased an Audi and want to avoid any common problems that may arise. Could you provide some insight on the most common issues with Audi cars and how to prevent them?

One common issue with Audi cars is engine oil leaks. To prevent this, make sure to regularly check and change your engine oil according to the manufacturer's recommendations.

Another common issue is malfunctioning fuel pumps. To avoid this problem, maintain your car's fuel system by using high-quality fuel and replacing the fuel filter regularly.
