Why is my Audi A6 making a loud clicking noise?

I recently noticed that my Audi A6 is making a loud clicking noise whenever I start it up. It doesn't seem to affect the performance, but I'm worried it could be a sign of a bigger problem. What could be causing this and how can I fix it?

This could be a sign of a faulty starter motor. It's important to get it checked and potentially replaced by a certified mechanic to avoid further damage.

It could also be an issue with the ignition system. I recommend taking it to a trusted mechanic for a diagnostic test to determine the exact cause of the clicking noise.

Make sure to check the battery connections and cables as well. Loose or dirty connections can also cause a clicking noise when starting the car.
