Check the state of the gimbals
One of the most regular triggers of a clicking noises in the direction of your Audi A8 is related to the direction of the automobile. Indeed, the cardans and their bellows are parts that are constantly stressed during your changes of direction or that you turn your wheels and a wear of one of them can create a ticking type of sound when you get closer to the stop zone of your steering.

If you encounter a clicking noise on your Audi A8 each time you pass a speed bump, it is really conceivable that your suspension block is the induce of the sound.

To examine if this is the issue that concerns you, take a dented road and, at low speed, listen to the sound originating from your front axle when you pass over holes. If these are the cups, consider changing them promptly as this may affect other parts and require more expensive repairs.
Check spring and cylinder
If you hear a clicking noise on your Audi A8 at the suspension level, it is highly conceivable that spring wear or shock cylinder deformation may be a cause. To examine the shape of the spring, position the car on a flat surface and measure that the heights from the ground to the bottom of the body are similar on each side (empty car for measurement). You can also examine between the front and rear, if there is a gap too significant it means that most likely your springs are worn, if you find out a leak go a little further in the article to have the solution to this problem. For the cylinder the verification is visual, make sure that it seems to work in a straight axis. And that there is no angle that would alter its proper functioning.
