Why does my Audi A8 produce a clicking noise when starting?

I recently noticed that my Audi A8 makes a clicking noise when I start the engine. What could be the cause of this and what should I do about it?

This could be caused by a weak battery or a faulty starter. Have a mechanic check the battery and starter to determine the cause of the clicking noise.

It could also be due to a dirty starter motor or loose connections. Make sure to clean the starter motor and check all connections to ensure they are secure.
