Being subject to recurring noise on your automobile tends to be frustrating, a automobile is so elaborate that it is generally difficult to locate its origin and even more so to find the part that produces it. If you have already experienced a clicking noise on your Mercedes Cla, we will almost certainly be able to help you. Indeed, our editorial staff decided to create this document in order to review the main causes of a clicking noise on Mercedes Cla. 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 origins of clicking noise on Mercedes Cla coming from your suspensions.
I perceive a clicking noise on Mercedes Cla located on my engine
Verify your high engine
If you perceive a clicking noise on Mercedes Cla, and this noise is located at the top of the engine, it means that it originates from your cylinder head and its associated parts. Two elements can be the triggers of these ticking noises on Mercedes Cla. Either the hydraulic pushers , generally it is because of their faulty “hydraulic catch-up” system that we will find out these clicking noises, generally 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 circumstance, remember to change them.
Verify your low engine
If you have founded the zone of origin of the Mercedes Cla 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 maintenance are very complex and most mechanics will advise you to change the engine of your Mercedes Cla.
Combustion problem
Finally, if you have the feeling that this clicking noise on Mercedes Cla is related to the combustion of your engine, there are three possible reasons of it. Verify the condition of your glow plugs which, if worn, can hinder the proper combustion of the fuel mixture. Then, it is conceivable 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 read this document which deals in detail with the different injection sounds on Mercedes Cla.
I perceive a clicking noise on Mercedes Cla in my direction
Verify the condition of the gimbals
One of the most basic reasons of a clicking noises in the direction of your Mercedes Cla 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 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 swapped rapidly, 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 Cla, do not hesitate to consult this complete guide.
Verify the rest of your direction
Finally, when you experience a clicking noise on your Mercedes Cla, it is conceivable 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 Cla coming from my suspensions
Verify the suspension
If you experience a clicking noise on your Mercedes Cla when you pass a speed bump, it is extremely conceivable that your suspension block is the induce 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 task 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, focus on the noise coming from your front axle when you pass over holes. If these are the cups, consider changing them quickly 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 Cla at the suspension level, it is widely conceivable that spring wear or shock cylinder deformation may be a reason. To check the shape 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 equivalent on each side (empty car for measurement). You can also check between the front and rear, if there is a gap too significant it means that most likely your springs are worn, if you observe 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 consider replacing it or them. If you have the feeling that this noise is more like a squeaking noise on Mercedes Cla than a clicking noise, don’t hesitate to consult this article.
