What should I do if my Audi A6's engine won't start?

I have an Audi A6 and for the past few days, the engine won't start. The battery seems fine and all the lights and electronics are working. What could be the issue and what should I do to fix it?

One possible cause could be a faulty starter. You can try tapping on the starter with a hammer to see if it will jolt it into starting. If that doesn't work, it's best to get it checked by a mechanic.

Another possible issue could be a clogged fuel filter. You can try replacing it to see if that resolves the issue. If not, it could be a more serious problem with the fuel pump or fuel injectors.
