What are some common problems with the Audi A4 fuel system?

I recently purchased an Audi A4 and have been experiencing some issues with the fuel system. I want to know what the common problems are and how to prevent them.

One common issue with the Audi A4 fuel system is a faulty fuel pump. This can lead to poor fuel economy and stalling out of the vehicle. To prevent this, make sure to regularly check and replace the fuel pump if necessary.

Another potential issue is a clogged fuel filter. This can cause a lack of fuel reaching the engine, resulting in poor performance and potentially damaging the fuel injectors. To prevent this, change the fuel filter per the manufacturer's recommended schedule.

Leaks in the fuel line or fuel tank can also occur in the Audi A4. These can be caused by wear and tear or corrosion. It's important to regularly inspect the fuel system for any leaks and have them repaired as soon as possible.
