Examine your low engine
If you have determined the zone of origin of the Mercedes Benz CLS Class clikcing noises coming from your low engine, it may be that your rods or piston shafts are the triggers.

Examine the state of the gimbals
One of the most common reasons of a clicking noises in the direction of your Mercedes Benz CLS Class 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 make a ticking type of sound when you get closer to the stop zone of your steering. A bellows with holes will damage the cardan shaft very quickly and must be swapped in a short time, otherwise the entire cardan shaft will have to be swapped. Consider taking a look at it.

Examine the suspension
If you encounter a clicking noise on your Mercedes Benz CLS Class when you pass a speed bump, it is very possible that your suspension block is the cause of the sound. Indeed, it may be the suspension cups, which, when they are dead, have the rubber (silentbloc) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its task and during small jolts that compress the suspensions. To check if this is the issue that concerns you, take a dented road and, at low speed, focus on the sound coming from your front axle when ever you pass over holes. If these are the cups, consider changing them soon as this may affect other parts and require more expensive repairs.
Check spring and cylinder
If you notice a clicking noise on your Mercedes Benz CLS Class at the suspension level, it is widely possible that spring wear or shock cylinder deformation may be a cause. 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 equivalent on each side (empty car for measurement). You can also check between the front and rear, if there is a gap too large it suggests that that most likely your springs are worn, if you discover a leak go a little further in the article to have the answer 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. If one of them breaks in both situations, you should think about swapping it or them.
