Is it normal for my Audi A6's engine to make a clicking sound?

I recently purchased a used Audi A6 and I've noticed that the engine occasionally makes a clicking sound. Is this normal or should I be concerned?

It is not normal for your engine to make a clicking sound. This could be a sign of an issue with your engine and it's important to have it checked by a certified mechanic as soon as possible.

If the clicking sound is only occasional and not accompanied by any other symptoms, it could be a sign of a loose belt or a valve issue. I recommend taking your car to a trusted mechanic for a thorough inspection.
