Being subject to repeated noise on your car tends to be disturbing, a car is so sophisticated that it is usually difficult to determine its origin and even more so to find the part that generates it. If you have already experienced a clicking noise on your Citroen C4, we will probably be able to support you. Indeed, our editorial staff decided to write this content page in order to review the main causes of a clicking noise on Citroen C4. This is why, firstly, we will check out what are the causes of this type of noise coming from your engine block, then those of a noise coming from your direction and finally, the sources of clicking noise on Citroen C4 coming from your suspensions.
I perceive a clicking noise on Citroen C4 from my engine
Examine your high engine
If you perceive a clicking noise on Citroen C4, and this noise is based at the top of the engine, it means that it originates from your cylinder head and its associated parts. Two parts can be the causes of these ticking noises on Citroen C4. Either the hydraulic pushers , in most cases it is because of their faulty “hydraulic catch-up” system that we will perceive these clicking noises, generally when cold and disappear when hot. Otherwise, it is the interplay of your rocker arms or their condition of wear that is at issue. In this circumstance, remember to change them.
Examine your low engine
If you have distinguished the zone of source of the Citroen C4 clikcing noises coming from your low engine, it may be that your rods or piston shafts are the causes. In both circumstances, the risk in the long term is the breakage of the motor. These two maintenance are very complicated and most mechanics will advise you to swap the engine of your Citroen C4.
Combustion problem
Finally, if you have the feeling that this clicking noise on Citroen C4 is connected to the combustion of your engine, there are three possible reasons of it. Examine the state of your glow plugs which, if worn, can hinder the proper combustion of the fuel mixture. Then, it is plausible that your timing belt is shifted and that it does not properly manage the timing of the various engine parts to promote good combustion. And finally, the most classic reason, comes from your injection, which is either blocked or one or more injectors are damaged. In this circumstance, do not hesitate to consult this content page which deals in detail with the different injection sounds on Citroen C4.
I perceive a clicking noise on Citroen C4 in my direction
Examine the state of the gimbals
One of the most common reasons of a clicking noises in the direction of your Citroen C4 is related to the direction of the car. 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 approach the stop zone of your steering. A bellows with holes will affect the cardan shaft very quickly and must be replaced in a short time, otherwise the entire cardan shaft will have to be replaced. Consider taking a look at it.

Examine the rest of your direction
Finally, when you know a clicking noise on your Citroen C4, it is plausible that it is the direction that is involved. Just like the gimbals, the steering part is mobilized when you turn your wheels. If this is the circumstance, the parts that may have been damaged due to normal wear and tear or impact (e. g. sidewalks) are steering rods, stabilizer bar silentblocks or steering triangles.
I perceive a clicking noise on Citroen C4 coming from my suspensions
Examine the suspension
If you experience a clicking noise on your Citroen C4 when you pass a speed bump, it is extremely plausible that your suspension block is the cause of the noise. Indeed, it may be the suspension cups, which, when they are out of date, 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 examine if this is the trouble that concerns you, take a dented road and, at low speed, pay attention to the noise coming from your front axle when ever you pass over holes. If these are the cups, consider changing them as soon as possible as this may damage other parts and require more expensive repairs.
Check spring and cylinder
If you hear a clicking noise on your Citroen C4 at the suspension level, it is widely plausible that spring wear or shock cylinder deformation may be a reason. To examine the condition of the spring, place the vehicle 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 see a leak go a little further in the article to have the answer to this problem. For the cylinder the verification is visual, be sure 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 replacing it or them. If you have the feeling that this noise is more like a squeaking noise on Citroen C4 than a clicking noise, don’t hesitate to consult this article.
