How can I troubleshoot my Audi A4 when it won't start?

I have a 2017 Audi A4 and it's been having trouble starting lately. The battery and starter have been recently replaced but the issue persists. What else should I check for to troubleshoot this issue?

Firstly, check for any possible loose connections between your battery and starter. Sometimes these can become loose during replacement and cause issues. You should also check your spark plugs and ignition coils as they may need to be replaced if they are faulty. It's also a good idea to have your fuel pump and injectors checked as well.
