How to fix an Audi that won't start?

I've recently encountered an issue with my Audi where it won't start. The engine makes a clicking sound but won't turn over. What could be the problem and how do I fix it?

The clicking sound could indicate a dead battery. Try jump starting your car and see if that helps. If not, it could be an issue with the starter or alternator.

Check your key fob battery and make sure it's not dead. If it is, replace it and see if that solves the problem.

There could be an issue with the fuel pump or fuel filter. Have a mechanic check these components if jump starting doesn't work.
