Being subject to regular noise on your automobile tends to be irritating, a automobile is so sophisticated that it is usually difficult to find its origin and even more so to find the part that produces it. If you have already experienced a clicking noise on your Mercedes Classe B, we will probably be able to support you. In fact, our editorial staff decided to create this content page in order to review the main causes of a clicking noise on Mercedes Classe B. This is why, firstly, we will look at what are the reasons of this type of noise coming from your engine block, then those of a noise coming from your direction and finally, the origins of clicking noise on Mercedes Classe B coming from your suspensions.
I find out a clicking noise on Mercedes Classe B from my engine
Verify your high engine
If you find out a clicking noise on Mercedes Classe B, and this sound 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 B. Either the hydraulic pushers , generally it is because of their faulty “hydraulic catch-up” system that we will find out these clicking noises, often when cold and vanish when hot. Otherwise, it is the interplay of your rocker arms or their state of wear that is at issue. In this case, remember to change them.
Verify your low engine
If you have distinguished the area of origin of the Mercedes Classe B clikcing noises coming from your low engine, it may be that your rods or piston shafts are the triggers. In both situations, the risk in the long term is the breakage of the motor. These two fixes are very complicated and most mechanics will advise you to swap the engine of your Mercedes Classe B.
Combustion problem
Finally, if you have the feeling that this clicking noise on Mercedes Classe B is linked to the combustion of your engine, there are three possible reasons of it. Verify 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 trigger, comes from your injection, which is either blocked or one or more injectors are damaged. In this case, do not hesitate to consult this content page which deals in detail with the different injection sounds on Mercedes Classe B.
I find out a clicking noise on Mercedes Classe B in my direction
Verify the state of the gimbals
One of the most common causes of a clicking noises in the direction of your Mercedes Classe B is connected 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 generate a ticking type of sound when you approach the stop zone of your steering. A bellows with holes will damage the cardan shaft very quickly and must be swapped very quickly, otherwise the entire cardan shaft will have to be swapped. Consider taking a look at it. If you would like more detailed information about gimbals noises on Mercedes Classe B, do not hesitate to read this complete guide.
Verify the rest of your direction
Finally, when you find out a clicking noise on your Mercedes Classe B, 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 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 find out a clicking noise on Mercedes Classe B coming from my suspensions
Verify the suspension
If you experience a clicking noise on your Mercedes Classe B when you pass a speed bump, it is extremely plausible that your suspension block is the induce of the sound. In fact, 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 function and during small jolts that compress the suspensions. To examine if this is the trouble that worries you, take a dented road and, at low speed, listen to the sound originating from your front axle when ever you pass over holes. If these are the cups, consider changing them quickly as this may affect other parts and require more expensive repairs.
Check spring and cylinder
If you detect a clicking noise on your Mercedes Classe B 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 suggests that that most likely your springs are worn, if you observe 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. If one of them breaks in both situations, you should consider swapping it or them. If you have the feeling that this noise is more like a squeaking noise on Mercedes Classe B than a clicking noise, don’t hesitate to consult this article.
