Why won't my Audi A6 start?

My Audi A6 won't start and all I hear is a clicking sound. It used to start up just fine before. What could be causing this issue?

There could be a few reasons why your Audi A6 won't start. One possibility is that your battery may be dead. Check the battery connections and make sure they are secure. You can also try jump starting your car to see if that resolves the issue.

Another potential issue could be with the starter motor or solenoid. If these components are faulty, it could cause your car to make a clicking sound and not start. It's best to take your car to a mechanic to have them inspect and potentially replace these parts.
