How to troubleshoot an Audi that won't start?

My Audi won't start. I turned the key and nothing happened. I checked the battery and it seems fine. What could be the problem and how can I fix it?

Your Audi may not start due to several reasons. First, check if all the connections on your battery are tight and clean. If the connections are fine, the problem may be with your spark plugs. Make sure they are not worn out or dirty. Also, inspect the starter and ignition system for any issues. If everything seems fine, it could be a problem with the fuel system.

I had a similar issue with my Audi and it turned out to be a faulty fuel pump. Have it checked by a mechanic to confirm the issue. Also, make sure you have a strong enough battery, sometimes a weak battery can cause starting problems.
