Being subject to frequent noise on your vehicle tends to be disturbing, a vehicle is so sophisticated that it is generally difficult to situate its origin and even more so to find the part that generates it. If you have already experienced a clicking noise on your Mercedes Classe C 2, we will almost certainly be able to support you. Indeed, our editorial staff decided to create this document in order to review the main causes of a clicking noise on Mercedes Classe C 2. 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 Mercedes Classe C 2 coming from your suspensions.
I perceive a clicking noise on Mercedes Classe C 2 located on my engine
Examine your high engine
If you perceive a clicking noise on Mercedes Classe C 2, and this noise is located at the top of the engine, it means that it comes from your cylinder head and its accompanying parts. Two elements can be the triggers of these ticking noises on Mercedes Classe C 2. Either the hydraulic pushers , in most cases it is because of their faulty “hydraulic catch-up” system that we will notice these clicking noises, often when cold and disappear when hot. Otherwise, it is the interplay of your rocker arms or their state of wear that is at issue. In this situation, remember to change them.
Examine your low engine
If you have distinguished the area of origin of the Mercedes Classe C 2 clikcing noises coming from your low engine, it may be that your rods or piston shafts are the triggers. In both circumstances, the risk in the long term is the breakage of the motor. These two repairs are very complex and most mechanics will recommend you to change the engine of your Mercedes Classe C 2.
Combustion problem
Finally, if you have the feeling that this clicking noise on Mercedes Classe C 2 is linked 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 possible that your timing belt is shifted and that it does not properly manage the timing of the various engine elements 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 case, do not hesitate to consult this document which deals in detail with the different injection sounds on Mercedes Classe C 2.
I perceive a clicking noise on Mercedes Classe C 2 in my direction
Examine the state of the gimbals
One of the most regular reasons of a clicking noises in the direction of your Mercedes Classe C 2 is linked to the direction of the vehicle. 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 generate a ticking type of sound when you get closer to the stop zone of your steering. A bellows with holes will affect the cardan shaft very quickly and must be replaced rapidly, otherwise the entire cardan shaft will have to be replaced. Consider taking a look at it. If you would like more detailed information about gimbals noises on Mercedes Classe C 2, do not hesitate to read this complete guide.
Examine the rest of your direction
Finally, when you recognise a clicking noise on your Mercedes Classe C 2, it is possible 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 case, 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 Mercedes Classe C 2 coming from my suspensions
Examine the suspension
If you encounter a clicking noise on your Mercedes Classe C 2 each time you pass a speed bump, it is extremely possible that your suspension block is the reason of the noise. Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentbloc) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role and during small jolts that compress the suspensions. To check if this is the trouble that worries you, take a dented road and, at low speed, listen to the noise coming from your front axle when you pass over holes. If these are the cups, consider changing them promptly as this may damage other parts and require more expensive repairs.
Check spring and cylinder
If you are subject to a clicking noise on your Mercedes Classe C 2 at the suspension level, it is highly possible that spring wear or shock cylinder deformation may be a cause. To check the condition of the spring, position the automobile 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 large it denotes 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, 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 consider changing it or them. If you have the feeling that this noise is more like a squeaking noise on Mercedes Classe C 2 than a clicking noise, don’t hesitate to consult this article.
