What are the common issues with the Audi A4 fuel pump?

I just purchased a used Audi A4 and have been experiencing issues with my fuel pump. It seems to be constantly failing and causing my car to stall. What could be the problem and what steps should I take to troubleshoot it?

Your fuel pump may be failing due to a clogged fuel filter. My advice is to replace the filter and see if that resolves the issue. If not, it could be a faulty fuel pump itself. Also, make sure to regularly clean and maintain your fuel system to prevent future issues.

I had a similar issue with my Audi A4's fuel pump and it turned out to be a faulty fuel pressure regulator. Replacing it solved the issue for me. I recommend getting it checked and replaced if necessary.
