Examine the suspension
If you experience a clicking noise on your Audi A4 each time you pass a speed bump, it is really possible that your suspension block is the cause of the sound.

To check if this is the trouble 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 soon as this may damage other parts and require more expensive repairs.

To check the state of the spring, place the car on a flat surface and measure that the heights from the ground to the bottom of the body are identical on each side (empty car for measurement). You can also check between the front and rear, if there is a gap too significant it denotes that most likely your springs are worn, if you see a leak go a little further in the article to have the solution to this problem. For the cylinder the verification is visual, ensure that it seems to work in a straight axis. And that there is no angle that would alter its proper functioning.
