What are some common issues with Audi's fuel system and how can I prevent them?

I recently bought a used Audi and I want to make sure I take care of my car's fuel system. What are some things I should look out for and how can I maintain my fuel system to prevent any major issues? Any tips or advice would be greatly appreciated!

It's important to regularly check your fuel filter and replace it if necessary. A clogged filter can cause issues with fuel flow and lead to expensive repairs.

Another common issue with Audi's fuel system is a faulty fuel pump. If you notice your car stalling or having trouble starting, it could be a sign of a failing fuel pump.
